After months of cute Caskett exchanges (and even some tense moments along the way) Castle Season 5 has finally come to a close. And as usual, the finale totally delivered. If you don’t want to be spoiled about a truly epic hour of television then look away!

After interviewing for her dream job in D.C., Beckett is forced to choose between Castle and her career — a choice made even more intense after Castle accidentally learns about Beckett’s interview and our gal gets the job.

Castle chats with Martha, who bluntly tells her son that “somewhere deep down inside you don’t think this is going to really work” and all signs point to a Caskett breakup, something even Beckett’s dad knows is coming. But then our favorite couple heads to the swings where it all began.

Beckett’s all ready to end things with her man and relocate to D.C., but Castle surprises his lady love with, wait for it, a proposal. Of course, in true Andrew Marlowe fashion, we don’t hear Beckett’s answer, but her shocked face says enough.

Will she accept Castle’s proposal, or will she call him crazy and head to D.C. on her own at the start of Season 6? Weigh in with your thoughts and theories below!
