'White Collar' Wraps Season 2 With a Billion-Dollar Explosion (VIDEO)

Sometimes the past can come back to haunt you, and sometimes it just comes to tease and entice you a little bit. In the 'White Collar' Season 2 finale (Tue., 10PM ET on USA), we got a taste of Neal's former life as a thief, and you know he's still drawn to it.

Unfortunately, there was a huge mishap in the art heist. And by huge, we mean that while Neal's former mentor was pleaded with him to help him get by Neal's own FBI partners with a truck filled with more than $1 billion of Nazi art, no one was watching the building the truck was in.

Peter put an end to Neal's dilemma by putting a bullet in Vincent Adler, officially closing that chapter in Neal's life. Or did he? The explosion supposedly cost the world all that art. But did it? A mysterious note at the end of the episode leads Neal to a storage locker. Its contents were?

The contents of that sunken Nazi U-Boat. Better turn that over to the Feds, right Neal? Wait. What does that devilish grin mean? See you in Season 3 to find out.
