S1, E2: 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). Alice takes Lorraine off to dinner to break the bad news; she's marrying Mitch. But how to explain the threeway daddy-mummy-daddy set up? Meanwhile, Mitch and Richie (having all jointly sworn off drink and drugs in solidarity with Alice) stumble across a stash of drink and drugs. Will they be strong enough to resist temptation whilst also assembling all the new nursery flat-pack? Or is it just an immutable fact of life that flat-pack is far more easily assembled on drugs?
