Mark's girlfriend finally reveals "her" secret; Ling and Nelle represent a woman suing a relationship guru whose advice ruined the woman's marriage; Ally is dating two different men who end up being related.

Ally runs into Kimmie Bishop, an old friend of hers from college. Ally makes fun of her in front of her fellow puritan friends, and Kimmie is so outraged she decides to sue Ally for defamation. Instead of having someone from the office to defend her, Ally hires therapist/lawyer Larry Paul. When Renee tells her he's married, Ally freaks. At the bar, while trying to decide if she would date a father or a son, she sees Larry with Nelle. Turns out he's divorced, and so Larry dumps Nelle to go out with Ally. Meanwhile, Mark is having a hard time at the office because nobody approves his relationship with Cindy, so he breaks up with her.
