'Castle' sneak peek: See Beckett's reaction to Castle's proposal!

Castle fans, you’ve been patient all summer. So here’s the moment you’ve been waiting for

Well, part of it anyway. We couldn’t go and give you ALL of Beckett’s reaction to Castle’s heart-stopping proposal, but the clip below, which you’re seeing exclusively on EW, is still a whopper of a sneak peek.

Our favorite part? The kiss. And Beckett’s mini freak-out. And when Castle asks, “You do know how this works, right?” And… well, we could go on. Watch below and react with appropriate enthusiasm in the comments. And to see the entire moment — including how Castle reacts when Beckett tells him about the job in D.C. — watch the Castle season premiere on Sept. 23 at 10 p.m. ET on ABC.
