Eric seeks help from Mary's (Jessica Biel, who does not appear in the episode) ex-boyfriend, Wilson (guest-star Andrew Keegan) after Charlie (guest-star Eric Panler), a new father, confesses to Eric that he has made a mistake and can't handle the responsibility of being a young dad. Meanwhile, Lucy and Kevin argue over which doctor they prefer, and Ben (guest-star Geoff Stults), who has taken an unusual interest in their pregnancy, only makes matters worse by siding with Lucy; and Ruthie has hidden intentions for wanting to hang out with Martin and his best friend Mac (guest-star Kyle Searles), which only leads to disappointment since Mac thinks of her more as a little sister.

Ruthie essaye de draguer Mac, avant de se rendre compte qu'il la considère comme sa petite soeur. Ben profite d'une consultation de Lucy pour sa draguer sa gynécologue. Eric essaie d'aide un père adolescent et appelle Wilson à la rescousse.
