I am still shaking with excitement and happiness. That was brilliant! So totally unexpected (I was expecting teasing, denial, and, stolen looks, but this was so much better!)

How serious Castle is when he says he's jealous! His pout is heartbreaking! Beckett's smile and telling him she thinks it's sweet (what is that, the 3rd time or so?)! The looks they share! Her telling him she's a one writer girl ("one-and-done", anyone???)! The "thank you" & the "always"! The way Castle sill stares at her adoringly for another 13 or so seconds after she turns!
