What the Chuck?! Exclusive Photos and Life-or-Death Scoop Straight From the Set

Romance, death and a surprising switch in loyalty pave the way for the final episodes

Ruh-roh. Looks like some major shockers are coming to Chuck, and they will blow your knee socks off.

I was just on set with Zachary Levi, Yvonne Strahovski and friends as they shot Chuck's two-hour season finale, and have some exclusive photos and scoop--some giddy good, some spine-tinglingly scary...

First of all, newsflash for you haters (boo) who haven't been loving the current season of Chuck with Chuck Bartowski (Zachary Levi) sporting his new spy skills: Everything you've seen so far is just a warm-up leading up to insanity in the final episodes of the season. Trust me, there is payoff for everything you've seen before.

After catching a peek at what will come in Chuck's final episodes, I can tell you there are some fantastic storyline surprises up ahead, including:

At least one death.

A switcheroo of someone's loyalty. (Please don't tell me it's Casey!)

Romance. (Please tell me it's Casey!)

And, no shocker here, but Zachary and Yvonne are looking pretty great as always. (The exclusive photos above and at right are from the season finale.) Chuck's two-hour season ender airs May 24.

Oh, and most important, as this photo below shows you...

More Agent Casey (Adam Baldwin)!

Yes, even though he was banished by the CIA in the latest episode, it seems Casey is certainly very much in the mix of the action as of the season finale. Unless he's checking showtimes with Mr. Moviefone for a bro-date with his new friend, Morgan (Josh Gomez)? Yeah, probably not.

Does the photo also mean Morgan is somehow in on the big action, too? That I don't know (sorry), but it would be pretty cool if you ask me.

Got guesses on these big twists? Who'll die? Who'll fall in love? Hit the comments.

And make sure you watch Chuck tonight at 8 p.m. on NBC to see how it all starts unfolding.
