When Mel skips school to visit her mother's grave (she won't explain why at first) her teacher Mr Coleman decides it's time to pay a home a visit. Meanwhile, Brian has developed an allergy that causes him to sneeze and morph uncontrollably. Mel starts training Sophie to behave like a 'real' mother, while Lucy attempts to diagnose Brian's allergy. Unfortunately, during his visit Mr Coleman sees Brian sprout a new nose and ears, and resolves to return with their social worker. Josh is determined to hold a party to improve his social standing – could this somehow save the whole family from being taken back into care? Will the world find out Brian and Sophie are aliens?

Brian decides that he and everyone else should become a proper family so Brian enters a quiz night, however Lucy doesn't want to join so she goes to join Wendy's team and ends up playing against her family who will win and what will happen?

Mel arrives home late and expects to be grounded by Brian and Sophie but isn't. She keeps trying to get into trouble until she comes home with a walkman she says she stole. Josh tries to get a date with Tanya Thomas (Zoe Thorne), so he enlists Brian's help. Brian morphs into Josh and asks out Tanya's friend, Denise, who fancies him. When the two girls meet each other on the day of the date, they both start hating Josh.

Lucy finds an injured dog, which she names Dennis, and starts nursing it back to health. Mel disapproves, warning Brian that Lucy will be upset when it dies. Meanwhile, Josh spends the money he raised for a charity event on a football ticket, and starts to earn the money back by putting up 'dog found' posters for Mel. When Lucy finds out, she pays him even more to bring them all back again, by which time Mel has warmed to Dennis and agrees to keep him. However, Josh returns with a 'Have you seen Woolly?' poster and Lucy and Mel realize that Dennis, a.k.a. Woolly, needs to go home to the people who are missing him.

When Lucy calls Brian and Sophie "Mum and Dad", Mel gets angry and shows Lucy and Josh a box of things she kept to remind her of their real parents. However, a lipstick is missing from the box. Lucy realizes that it was she who had taken it and swapped it, so she must ask Josh for help. Meanwhile, after a string of Fs, Josh must resit his exams or be put back a year. To pay him back for helping with the lipstick, Lucy helps him revise, and discovers that he may be dyslexic.

Lucy discovers she and her best friend are 'geeks' after they are the only two girls in the class not to be invited to a party. Mel gives Lucy a makeover, but this threatens to alienate her from Wendy, with whom she has been studying caterpillars. Sophie is struck down with a case of the flu, but enjoys her freedom from housework and responsibility and hides her recovery. Lucy decides friendship is more important than being 'cool', and she and Wendy discover that their caterpillars "were really butterflies all along."

When Lucy wins tickets to see Blink 182 in a competition, Josh is desperate to take them off her hands – after all, he's a huge fan of the band, and Lucy's such a geek she's never even heard of Blink 182. Lucy agrees to give the tickets to Josh, but on one condition: Josh has to perform a truly unselfish deed in order to qualify for the tickets. Of course it's a terrible struggle for the scam-meister, but Josh learns a whole lot about himself in the process. Elsewhere Mel is upset (though refuses to show it) when Trent appears to be going on a date with another girl. The confusion is resolved later in the episode when it turns out that Kelly is Trent's cousin, not his date and he and Mel become friends again.

Josh injures himself during sports, so Brian attempts to fix him with a home-made machine. However, the machine instead makes Josh a chess champion and a maths prodigy by mistake, making Lucy feel threatened as she is outplayed in chess.

Josh wants to have a wild party for his class (including resident tough-guy, Big Verne) so he tries to make the rest of the family go on a holiday. Mel is aggravated by her family's constant need for attention when all she wants some privacy to write a song to enter into a competition with Trent.

Lucy and Wendy are on the verge of falling out, as Wendy is upset that Lucy never invites her to her house. They arrange a sleepover, and Sophie and Brian must act as normal as possible. Meanwhile, Josh is charging Sophie for doing chores around the house so that he can later buy a snooker table.

Lucy is selected to represent the school in a Science Tournament where she has to build a rocket with maximum propulsion – which proves to be too difficult a task for her, so Sophie offers to help. Brian enters one of Mel's photograph's in an art contest. Josh tries to bribe Scott Taylor into letting him join the football team and get to go to Holland and almost loses Frankie and Pete as friends.

Mel goes to school in trousers, as she feels the school rule that girls must wear skirts is sexist, whilst Lucy is looking after the school hamster which Josh promptly loses by trying to make some money with it.

Lucy manages to get her way in the house, organising chess nights and debates. Due to this, Josh gets the idea to run for school council. He claims if appointed, he would get all students entry to the prefect's room, much to the anger of Mel. Mel has a secret weapon – if he continues in his plan, she will blackmail him with a karaoke tape of him singing along to Britney Spears. But then when she puts it on in the school Josh starts to sing and everyone gets dancing so Mel gets annoyed and leaves with a sulk.

Lucy's birthday is arriving, and she wants a party. While she thinks no-one is interested, the family is planning a secret party.

Brian and Sophie become hooked on a trading card game, and will go to any lengths to obtain more cards. They end up stealing and selling the school laptop.

It's Valentine's Day, and Josh is trying to get a date with Tanya Thomas, but makes the foolish mistake of taking Brian's advice on matters of the heart. Mel is the object of desire of Andy the Freak and Frankie when all she wants is a 'joke' Valentine's card from Trent. Sophie follows her heart and writes a card to her true love: the dishwasher. Sophie asks the family what Valentine's Day is, but in an episode a few years ago when Barbara Durkin played Sophie she is trying to act calm in front of a teacher who has come to visit the house and she says "This happened to me once on Val.... Valentine's Day".

During this episode there is one of the many obviously romantic moment between Mel and Trent when they almost kiss in Mel and Lucy's bedroom.

Brian and Sophie adopt a new child: Howie. Howie turns out to be a safety freak, much to the exasperation of Mel, Josh and Lucy.

When Lucy gets in trouble with one of her teachers for apparently copying homework, Brian and Sophie discover the power of punishment. Poppy writes an article in the school magazine criticising Josh. Mel accidentally kills the school budgie and Josh writes this in his own school magazine. To get revenge, Mel gets Brian to morph into Josh and take naked pictures of himself to give to Poppy to print in her magazine.

Today Mel is fed up with Lucy's controlling behaviour and decides to move out of their bedroom and into the attic. Sophie sees this as the perfect opportunity to step in as Lucy's new sister. Lucy is incensed, but when Sophie and Wendy abandon her too, she begins to wonder whether she might be in the wrong after all. Josh is desperate to scam Frankie's signed united football shirt from him, and Brian agrees to morph into Mel as part of a cunning plan. But Josh is about to get a taste of his own medicine for once.

Brian feels rejected when Sophie chooses to watch repeats of Geoff Jefferson, Criminal Prosecutor, on cable TV, instead of taking part in his indoor Olympic Games.

Lucy cuts the cable on the TV to end the suffering, but it ends up with Sophie putting Brian's pet rat on trial. Brian is devastated, so tries to put the blame on himself. Lucy then admits and ends up being captured and rescued on the same night.

Brian has a new pet: Fluffy the goldfish, but when she's fed on a diet of fried egg, bacon and beans, the unfortunate Fluffy soon floats off to the big fish tank in the sky, leaving Brian devastated. He then holds a funeral for his beloved Fluffy, which goes well. Josh attempts a challenge at the diner: eating 50 courses. He asks Brian to morph into him, and eat 48 of the courses. The first course is fish fingers, devastating Brian. He quits, leaving Josh to eat all the food. Mel later takes out insurance with dozens of spare goldfish, which she stores in the bathroom, and Brian thinks that the new fish is Fluffy back from the dead.

Josh is confident that his "treat 'em mean, keep 'em keen" tactics will eventually win the heart of his school friend Tanya. Sophie decides that humans tell lies all the time, making her highly suspicious of everything her family says. Mel persuades Trent to let her stand in for him as school magazine agony aunt, but can she really summon up as much sensitivity as he does? Mel's determined to prove to him that she can. In a desperate bid to prove to Josh that he can lie convincingly, Brian tells Pete that Tanya fancies him. But when Pete and Tanya arrange a date, Brian has some quick thinking to do before Josh's heart is broken. Brian discovers that lying can cause a lot of trouble, while Mel finds out that telling the truth can, too.

When Lucy insists that there's no such thing as luck (it's all just a question of mathematical probability), Brian is determined to prove her wrong. He purchases a pair of Josh's 'lucky' underpants and is delighted to immediately win a free pen and a pound.

Josh is woken by a trumpet-playing Brian and is offered tiddlywinks for breakfast. His sisters may be technically human but they still can't behave like normal people. Why can't his family just be different in every way? A bump on the head makes Josh's wish come true, throwing him into a world of complete opposites. Lucy is stupid, Mel cares about what she looks likes and fancies Frankie, Sophie doesn't even try to be a good mum, Pete is short and fancies Mel and Frankie is tall doesn't like Mel but all of the other girls fancy him. Wendy is his girlfriend and like Lucy, is thick, but more clumsier than Lucy. And Mrs. Hardman is the art teacher and fancies Brian. This leaves a whole world of confusion and he wishes that he could have been fostered by someone else.

Meanwhile, the opposite Lucy and Wendy, are trying to write a story to win a day with Chubby the Bear but don't write much. And when Sophie enters too, Josh has to stop her from entering.

Lucy and Wendy have an argument that might end their friendship for ever. Josh has laryngitis, but despite Sophie's best efforts to nurse him back to health, he quickly loses patience with her bedside manner. Sophie finds that being ignored can make you feel like you don't exist at all. Brian is jealous that Trent has given Mel a music festival ticket and morphs into 'Spam' – a hip and trendy girl that will catch Trent's eye.

Brian resurrects the musical as BRIAN: The Musical. Sophie thinks that Josh has Parental Neglect Syndrome and follows him around school. Sophie then watches the Sound Of Music and learns how to really be a good mother. Mel has a bet with Trent that she couldn't last four days without insulting anybody but in the end it is Trent that breaks first and begs Mel to be mean again because that's the way he likes her!

Brian is desperate to join Lucy at the Brownies, but she refuses for obvious reasons. Undeterred, Brian forms his own association – The Brianies – with its own code of conduct. Meanwhile, Mel has got a job at the diner with Sophie later joining her to help her out...with some disastrous results.

After Brian accidentally leaves the front door open, Brian and Sophie come home to find all their furniture stolen. Brian responds by morphing into 'The Cat' to steal furniture from other homes, and this becomes his latest hobby. Josh discovers Brian's secret and (predictably) uses it to his own advantage.

Brian decides to give the attic, now filled with a bed, cinema screen, drinks cooler, &c., to the member of the family who loves him the most, but Lucy walks away from the contest, saying she loves Brian as a father, "no more, no less". Josh and Mel then compete in vain to win Brian's affections. Meanwhile, Sophie tries to boost her self-esteem. Based on Shakespeare's King Lear.

Lucy is horrified to find a wart growing on her face. But not as horrified as Brian, who has discovered the real purpose of the bath; he develops a taste for shower gel and is obsessed with hygiene-until he starts shrinking!

Sophie decides to accompany Lucy to advanced mathematics classes after school, but it soon becomes clear that Sophie has fallen in love with Mr. Whiteside, the teacher. Brian feels that he is losing Sophie (and her ability to cook disgusting meals which deeply satisfy Brian) to Mr. Whiteside, so he sneaks into school and kidnaps Mr. Whiteside, and then morphs into Mr. Whiteside himself, to try to pretend to Sophie that Mr. Whiteside is "evil". Unfortunately his plan is ruined when Sophie invites Brian and Mr. Whiteside to have a meal together with her.

When this problem is sorted there is one more problem to be solved, Harry entered Brain as a pigeon into a race where he has to make it home again from the starting line and he hasn't found his way home for days. Three days after Brian was sent into the race he returns to find that everyone loves him and is glad to see him.

Harry does her best to stop Brian and Sophie inviting Trent's parents to tea. Harry learns a "shocking" secret about Trent, Sophie gets into growing vegetables and Brian gets into football.

Sophie learns about gossip and thinks that Mrs. Hardman and Mr Whiteside have fallen in love with each other. Brian finds a human toe in his can of cola and finds out the drink was faulty and complains before he tests CJ’s eyes and discovers that he too is ‘faulty’. Josh competes in a snail race against Poppy, and the winner gets £5. Josh is convinced he'll win but when his snail is about to win Mrs Hardman comes in and Josh accidentally sits on his snail (Lenny) killing it.

Sophie has discovered how pollen from flowers can give you hay fever and almosts destroys all plants. But with an explanation from Lucy about how flowers are good for the atmosphere and for bees to make honey, Sophie decides to set up a bee sanctuary in the house. Meanwhile, Brian (morphed as Josh) has ruined Josh's reputation by becoming Mr. Whiteside's school monitor and putting people like Harry, Frankie and his date Tania Thomas in detention.

Mel finds out that the children have or had an aunt and uncle in Canada who look suspiciously like Brian and (the original) Sophie. They confront Brian and Sophie, who admit that, seven years ago, they met Josh, Mel and Lucy's aunt and uncle at the children's home – and then, after the aunt and uncle realized that they were aliens, the aunt and uncle were kidnapped and kept in suspended animation in the attic for seven years. The children insist that they let them free. Meanwhile, Wendy discovers Brian and Sophie are aliens, and she tells Pete and Frankie too, so Brian wipes their memories. Everyone realizes that it is time to move on. Josh, Mel, Lucy, Harry and CJ all move to Canada with the real Brian and Sophie Johnson, and the aliens appear to go back home to Valux; however, Brian presses the big red button that caused the pair to crash-land on Earth in the first place setting the stage for series 8. They land by the sea and then head for the foster home.
