Desmin Borges is a vital part of what makes "You're the Worst," one of TV's most exciting comedies, so very good. The FXX series deals with serious topics in darkly amusing ways, and that includes Borges's character, Edgar, a veteran who suffers from PTSD and is trying to struggle through it without much support from his friends. Borges joined me to talk about his research into PTSD, the moment that made him realize he wanted to be a performer, and his secret dining nirvana in Los Angeles.
