Cathy (Laura Linney) is worried about Lee's (Hugh Dancy) health but helps him with a few things on his bucket list by getting him a bottle of wine and letting him cop a feel of her bare breasts. What are "mole-mates" for? And Sean (John Hickey) is not coping well with losing baby Cathy - he's off his meds which makes him more vulnerable. Poppy (Parker Posey) and Adam (Gabriel Basso) continue to hang out but it's a little weird when she takes him to her high school 1990 Class Reunion.
