Piper Perabo Piper Perabo

To kill or not to kill?

That's the dilemma Annie (Piper Perabo) is faced with on Covert Affairs' Season 5 finale (Thursday, 10/9c, USA). Joan (Kari Matchett) wants Annie to bring Belenko (Shawn Doyle) in alive, but with the Russian Vega Force cornering them in Buenos Aires, McQuaid (Nic Bishop) thinks they should cut their losses, so to speak, to ensure his and Annie's safe escape. Annie, though, is a bit torn.

"Why does Russia want you dead now?" she asks Belenko in the exclusive sneak peek below.

"I know everything about how the FSB works, their infrastructure," he says. "You're going to keep me alive for the very same reasons the Russians want to kill me."

Regardless of Annie's decision, the finale will be a "very emotional" hour, co-creator and executive producer Chris Ord tells TVGuide.com. "In terms of emotion, we feel the whole season has been leading up to this episode. If you go back to the premiere, the Annie she was then, then comes McQuaid ... we felt we owed the audience to take this home in this episode, and answer questions fans might have but raising new ones."
