It was the episodes of all episodes on the Castle Season 5 finale, as Rick Castle (Nathan Fillion) asked Kate Beckett (Stana Katic) to marry him and we were all left with the whole summer to find out what he answer will be! Will Beckett say yes or no on Castle Season 6??? It appears no one knows, not even Castle star Nathan Fillion! Check out some Castle Season 6 spoilers below!

CASTLE - "Watershed" - In the Season Finale, an interview with a high-profile federal law enforcement agency forces Beckett to reconsider what she wants out of her job -- and out of her relationship with Castle. Meanwhile, the body of a young woman is found floating inside the water tank of a skid row flop house, but as the team investigate, they discover that her final resting place is just one of many strange things about her death, on "Castle," MONDAY, MAY 13 (10:01-11:00 p.m., ET) on the ABC Television Network. (ABC/Richard Cartwright) STANA KATIC, NATHAN FILLION

In an interview with TVLine, Fillion was asked about the cliffhanger we were all left with and it appears that he doesn’t even know what the answer will be:

“We did not shoot the answer. We did that last day of shooting on a Thursday. Friday, I came in and did some looping…and then left town immediately [to] work in Canada. I have no idea, not a one. I’ve not had one email, not one discussion, not a phone call about where things are going, what’s going to happen.”

So, I guess the Castle writers are keeping that information on lockdown, huh? What do you think the response will be from Beckett? Things will be quite interesting for the Castle Season 6 premiere that is for sure!
