A celebration brings the whole group together but as always, it doesn't go to plan.

It's Freddie and Stuart's anniversary party and they're expecting a long awaited guest.

Freddie and Stuart invite Ash and his new girlfriend Chloe to dinner.

After Freddie and Stuart have a falling out, Stuart moves in with Ash and Violet moves in with Freddie.

Violet panics when her wealthy sister Lillian plans a visit. Ash wants to introduce the group to his new girlfriend, Jess.

The gang decides to join Ash and Jess at a ballroom dancing class. Nimble on his feet, Stuart quickly becomes teacher's pet, leaving Freddie in a huff, while Violet becomes a hit with the amorous teacher in other ways.

Freddie and Stuart go shopping for a new coat for Freddie's Dr Who fan club event. Meanwhile new neighbour Ash seeks advice from Violet and Penelope on winning back his ex-­girlfriend.

Ash invites Freddie, Stuart, Penelope and Mason to go clubbing, which Freddie and Stuart turn into a popularity contest. Meanwhile, Violet arranges to go and visit her latest online suitor... even though he lives in Argentina.

Feeling unfit, Freddie and Stuart join Ash at his gym, where a young fitness instructor persuades the pair to sign up for an expensive membership. With Freddie and Stuart spending so much time at the gym, Violet and Penelope discover how pleasant their flat can be without the bickering pair in it.

Finding themselves both single, Violet and Ash consider dating new people, Violet has already met someone on the internet, while Ash's ex Chloe returns. Freddie, meanwhile, feels under pressure from Stuart to land a new acting role.

Freddie has an important audition coming up whilst Ash frets over his own career direction. Freddie suggests that Ash pursues acting and teaches him the tricks of the trade. But, when Ash secures an acting role after just his first audition, Freddie is thrown into a state of depression. Meanwhile, Violet seeks advice from Freddie and Stuart on her sordid love affair with her Hungarian boyfriend.

Freddie and Stuart are hosting a wake to mark the passing of an old friend. As they are joined by their small circle of elderly chums, the couple manage to create a toe-curlingly awkward evening with very little food but plenty of insults. Their new young upstairs neighbour Ash - whose sexuality becomes a point of great debate - spends the evening attempting to be the perfect guest, while fending off the advances of Freddie and Stuart's best friend Violet.
