Josh looks after his new sister and also attempts to charm his his new housemate.
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.
