Next Sunday marks the Revenge Season 3 finale, Season 3, Episode 22 ("Execution"), and after this week's shocking twist, we're more confident than ever that this episode will be one for the record books. If Conrad's (Henry Czerny) incarceration isn't enough to have you dying for the next episode, this new sneak peek of the episode might do the trick.

In this clip, Emily (Emily VanCamp) scopes out the cabin where the weird man obsessed with David Clarke is holed up. We can't say we're surprised; after Jack showed her that ring in Episode 21, there's no way Emily wasn't going to track this guy down. Who is he? What does he know about her dad?

This clip doesn't answer those questions, but it does tell us one thing: he knows how to fight. In this video, he surprises Emily while she's snooping around, and they immediately jump into an intense hand-to-hand combat sequence. Em wins the fight, but not before her opponent manages to stab her in the leg with a needle. We can only assume that it holds a tranquilizer — or worse.

Check out the sneak peek here!
