A thing from last night's White Collar episode

tuppence1 pointed out in the comments to my last post ( spoiler for the very end of WC 3x14 )

I had a thought! (Quick, catch it before it gets away!)

This is pure speculation on my part - I am (almost) completely unspoiled for the last two White Collar episodes of the season (I haven't even seen the promos) and would like to remain that way. PLEASE DO NOT SPOIL ME. Speculation is welcome, however. :D
