Craig insists the flatmates host a flat-warming party but the landlady finds out.

When Yasmin, the waitress he fancies, tells Craig about a wild party she went to, Craig decides they have to throw one. He leaves the planning to Lauren and Declan, but invites Craig 2, his Megabowl boss, as he wants to show off his DJ skills. Lauren tells Declan she's going to bring a date. He acts cool but clearly wants to get back together.

Craig's landlady surprises Lauren and Declan as they're setting up - she had no idea he had flatmates, let alone parties. But she doesn't stop them. As the party gets under way, misunderstandings pile up. Lauren's date, a guy from work, turns out to be bi-curious and kisses a surprised Craig; Declan sings, beautifully, to impress Lauren (and succeeds); Yasmin, the waitress, sets her sights on Declan, not Craig; and worst of all, the landlady reappears, joins in the party - and turns out to be Craig's mum!

Angry and upset, he tells her she can't be part of his life. It seems to have been a disaster - Declan and Lauren, if not reunited, are at least happier being around each other.
