How will Charlie handle being Jangles' abductee? Read on for the spoilers per TV GUide:
It won't be all good news for Charlie (Vanessa Ferlito) in the finale, as she reaches a boiling point in her close working relationship with Cortez (Vincent Laresca), who unbeknownst to her is actually the killer Jangles. "Charlie's story really, really reaches a crescendo ... and the story of what happens with Jangles — that sort of becomes the big event in the finale," Eastin says. "Mentally for Charlie, she really goes on an emotional roller coaster, just being deluged with all this information that Mike was there as a rat, the discovery that Cortez is Jangles, and then there's a surprise at the end where she reaches a point where she doesn't think she can go on being an FBI agent."
