Dylan must contact all the girls he has slept with to inform them he has chlamydia. He casts his mind back to Abigail and a flashback reveals a defining moment he'd tried to forget...

In a flashback to three years earlier, it's Evie's birthday and she plans to tell Dylan about her feelings for him over a quiet dinner, but the evening gets hijacked by their friends.

Dylan looks at a flat with Abigail, and Luke goes to therapy. Three and a half years ago, Angus and Helen are engaged -- and at each other's throats.
