Dollhouse

A pop star (Rayna) is performing in a concert when one of her back-up singers is set on fire by pyrotechnics... or the creepy Ginger Kid watching from the audience.

Echo's handler has recovered enough from his arrow wound to get back to work. Rayna's manager hires Echo out to serve as a back-up singer for Rayna, whilst also undercover-protecting her.

Another Active, Sierra, gets sent in as a contest winner who gets to hang out backstage. The Ginger Kid tries to shoot Rayna at another concert. Turns out Rayna's a little nuts, and was communicating with her stalker, and was hoping he'd kill her. In the end, of course Echo ends up catching the bad guy and saving Rayna.

The Russian guy that Agent Helo has been trying to get "Dollhouse" information from is revealed to actually be an Active, Victor. That was cool and unexpected. So he's putting Helo on the wrong track, including getting him shot.
