Murphy and Felix come up with a plan on Into the Dark. "How to Succeed in Business Without Really Dying" is the ninth episode of the show's second season.
Murphy is in quiet contemplation as she listens to something on her headphones and probably ponders what she can do make things right with her best friend.
Joy: Please tell me you're done with all this crime stuff. Murphy: No, I actually decided I'm going to become a detective. I'm going to put a little Sherlock Holmes hat on Pretzel, and we're going to solve murders.
