Deena's mother, Frankie, comes for a visit and, like everyone else, is unaware that Dave and Deena are back together. Now that Brian has broken up with Bridget, he gets separate invitations from his two attractive downstairs neighbors. Meanwhile, against Natasha's wishes, Brian assigns a big presentation to Dave; Adam and Nicole deal with the aftermath of their unexpected tryst; Dave gets into a fist fight with Deena's ex-lover; and the friends get a surprise when they visit Ivy and Jimmy's home for the first time.
