Josh has decided that Geoffrey is just too intense and has broken up with him. Meanwhile, Rose has decided she wants to try online dating. With some tips from Josh, it doesn't take her long to land a date. She meets Rod, an affable but not-very-interesting Rotarian with very few redeeming features, who takes her to an all-you-can-eat buffet restaurant for their first date. With his mum out on a date, Josh and Tom hijack Claire from a costume party and decide to head out for the sort of fun night they used to have before partners got in the way. But Josh hadn't counted on the budding romance between his only two friends. Josh does his best to make himself scarce by chatting to a nice guy at the bar. Everything looks to be going his way, until the bar guy's friends, who clearly don't approve of Josh, step in. A crestfallen Josh returns home alone, but his night may not be over.

Josh's 21st birthday is lost among preparations for a funeral. When Alan drops by to check up on Rose, he's pleased that she seems the most stable she's ever been. She is active, focused and surprisingly calm, and she insists on meeting Mae and inviting her to the funeral. In church, Claire entertains Rose with embarrassing stories about Josh to keep her distracted before the service. Niamh also arrives uninvited and sits up the back with Geoffrey, who has no choice but to comfort her. Back at Rose's house, the wake is an awkward affair. Dad has found himself in a conversation with Rod that can't be anything but a disaster, Niamh is annoying everybody, and Josh is happy for Geoffrey to be there, even though they have just broken up. While Rose's celebrations for Josh's birthday don't quite go according to plan, it's definitely going to be a birthday Josh won't forget.
