The finale picks up a couple of months after the last episode's big event, when Jill (Jaime Pressly) learned she's pregnant. The friends are sharing at one of their 12-step meetings: Tammy (Kristen Johnston), who has established a successful construction business with Bonnie, talks about dating a guy who is "sweet and and funny and supportive" and Marjorie (Mimi Kennedy) celebrates "the most wonderful weekend" babysitting her granddaughter after reconciling with her long-estranged son.
Jill, now four months pregnant, is thrilled to be expecting but also complains of frequent bathroom trips – "I am peeing like a broken sprinkler."
The positive vibes only make matters worse for Shannon (Melanie Lynskey), a miserable meeting newcomer. She bolts and Bonnie, once a model of self-absorption, follows to check on her, a sign of her growing maturity and concern for others.
