Alice turns 30. The three have a drug-addled threesome. Alice gets pregnant. She and Mitch decide to get rid of it. Mitch changes his mind. Mitch and Richie race to stop Alice at the clinic. More happens but that would spoil it before you see it.

And now our threesome have to figure out how to explain their unusually triangular relationship to the world. And most crucially – to Alice’s domineering and not entirely nice mother Lorraine (who is not fond of Mitch but adores Richie). But how to explain the threeway daddy-mummy-daddy set up?

Alice, Mitch and Richie attend their first antenatal class. To everyone’s surprise Alice and Richie are hopeless and Mitch is an amazing proto-father. Alice and Richie go into panic mode about their suitability as future parents, and so Mitch entrusts them with a robot baby from the antenatal class to practice on. All they have to do is feed it, rock it, change it – and not totally destroy it.

Mitch still hasn’t got a job, and now his lack of funds is starting to become a problem. Alice needs reliable support more than anything right now – the full reality of what’s about to pop out of her in six months time is starting to hit home, and with the impending 12 Week Scan they’re actually going to get to see their baby for the first time. It’s time for Mitch to step up to the plate. Unfortunately for Mitch, he spectacularly fails to do so.

To Alice's amazement - Richie and Dave are now dating! Proper boyfriends and everything. With Richie's birthday approaching a day of fun, fun, fun is being planned. But when Dave reveals he has alternative plans for Richie, tensions arise between the friends as Alice and Mitch conspire to keep Richie to themselves.<br /> <br /> When plans backfire, Richie ends up leaving Alice and Mitch to spend the day with Dave, who unveils his own special birthday surprise. But that means Richie leaving Alice and Mitch on the night they've planned so hard for so long to make special. Who is Richie going to choose?

Alice, just a month from popping, has decided to throw a baby-shower, and so Lorraine (Alice's mum), Sue (Mitch's mum) and Jenny (Richie's mum) converge on the flat to deluge her with presents and attention. Alice in turn has taken to baking, not-swearing and dressing like a proper woman. Mitch and Richie are horrified.<br /> <br /> Mitch and Richie escape for the evening to a local bar, and run into Wendy; a ballsy, feisty, fabulous girl who reminds them very much of a pre-pregnancy Alice. Spending time with Wendy is wonderful, but it's like cheating on Alice.<br /> <br /> Mitch and Richie vow to call off the 'affair', but when Princess Lullaby Dreamtime - a nauseating baby shower gift - arrives in the flat, the combination of that, Alice and The Mothers are more than Mitch and Richie can bear. How long can they hold out before they're drawn back into Wendy's arms, and how will Alice react when the two women finally meet?

The threesome prepares for Alice's 'Final Push Party' with some questionable costume choices from the boys...
