Clodagh's birth mother Carol comes to see her with news that her husband Tom is on the warpath and looking for Clodagh's father, Frederick - the man he believes to be responsible for ruining his life. Upset, Clodagh turns Carol away but later at The Clinic Tom shows up and won't leave until Clodagh hears him out. He becomes physically threatening and Lorcan has to step in to remove him from the premises. Carol returns to beg the shaken Clodagh not to get the Gardaí involved and, while Clodagh agrees to this request, she decides its best not to talk to Carol anymore.

Daisy and Cara vie for the position of Practice Manager, while two suitors - Conor and Adam - compete for Daisy's affections. Meanwhile, Dan has an uncomfortable run-in with Emer - his nearly one-night stand - outside the Clinic and finds out that she is one of Lorcan's free-clinic patients. Elsewhere, Patrick asks Bernie to move in with him.

Bernie moves in with Patrick, but she soon realises that he isn't ready to co-habit. Meanwhile, new practice manager Cara struggles to cope without a receptionist and Kieran cannot cope without Molly and leaves baby Hope with Cathy. Elsewhere, Dan and Cathy look at a property in the country and Emer has delusions over her relationship with Dan.
