Elliot was questioning abuse victim Kim Garnett's father
Elliot: What I'm saying is I got teenage daughters too, and I know how they can push your buttons. Hm? Stay out late, date guys you don't like
Olivia brought in Kathleen to jail to talk to Kim to admit that her boyfriend has been abusing her and to press charges. Kathleen used her troubled days when she needed help as an example to get through to Kim.
