Listen up, Castle fans! Season 3's finale not only promises another possible Castle and Beckett lip lock, it also marks the end of one character’s life. Their finale, if you will.

TVLine is reporting the May 16 episode, “Knockout,” will include a visit from the Grim Reaper for one character who has been around “since the beginning.” Nobody’s naming names, but TVLine says the show is “pulling out the big guns” for this one, and we’re guessing no matter who gets the axe, it’s gonna leave a lot of fans upset. Susan Sullivan (Martha) recently told Wetpaint exclusively that the finale would "involve love and loss," while Ruben Santiago-Hudson (Montgomery) believed that the writers were "probably looking for a huge cliffhanger at the end that’s going to shock everybody."

Wetpainters, who do you think will cash in their chips (figuratively speaking) during the finale?
