Welcome to the Dollhouse

Jane and Maura are on the case of a killer that dresses his victims as 1980s dolls. Meanwhile, Korsak finds a dog that turns out to be a dog for soldiers with PTSD, the dog works at the same place that Casey works at. When Maura brings the dog back she realizes what is wrong with Casey, and why he doesn't want to see Jane. Maura tells him that he must tell Jane about his injury. Angela starts a blog about the crime going around, with the website set up by Frost. The killer ends up being the son of a cop, whose wife had gone missing years ago. He had gone mental from watching his father kill his mother, and was trying to get someone to tell the police about what had happened. Maura tells Angela about Casey, and makes her swear not to tell. Soon after Jane gets a message from Casey wanting to meet. It turns out that Angela had written Casey, as if from Jane, saying that she accepted him and it didn't change anything. Jane explained that she would've said the exact same thing. Casey agrees to meet with Jane on a date soon.
