ABC's hit crime TV series, Castle, continues to draw massive speculation over the potential holy union between Castle (Nathan Fillion) and Beckett (Stana Katic).

Now gearing up for the program's sixth season, many of the show's loyalists are in dire curiosity over whether or not Beckett will be accepting the novelist's marriage proposal or move on to a career opportunity in Washington, D.C.

Although Fillion seemed to be in the dark over Caskett's fate, Katic claimed to Entertainment Weekly that she indeed knew Beckett's answer to the marriage proposal, but wasn't about to spill the beans.

"I know the answer, and I'm not telling you ... I think that her answer is the perfect one for the character and for the show. I think it has been long enough for a yes or no answer. I figure the intense situations they've gone through together has sped up their bond," she said.

Although no airdate has yet to be officially revealed, all indications point to ABC's Castle starting up again either on Monday, September 23 or the week after, according to Carter Matt.
