You want to know what hurts the most? You could have come to me with everything. Broken us up just like you did only it would have been a cover and together, in secret we could have taken this guy down but that thought never even occurred to you because deep down inside you like being broken and you need this obsession and no matter what I do I can't change that, only you can, Kate.
Castle: The fact that you even think that breaks my heart. I would walk into a tornado for you, Kate.
Beckett: And I would die if I lost you.

You know when I hung up my shingle as a P.I., I knew I'd have to follow some wives, I just never thought it would be my own.
Esposito: So you're going full hipster now.
Ryan: Have you started jarring artisanal pickles yet?

Beckett: Then don't change, ever.
No relationship can survive secrets or lies.
Castle: They've been through way too much together to give up on what they have.
Beckett: You're a wise man Castle, with a big heart and you're rather good looking too.
Castle: You might want to pace yourself with the flattery. You've got a whole dinner to get through.
Looks like someone did not enjoy getting screwed, out of their money that is.
You're supposed to be our buffer. Buff!Ryan
Castle, nothing you do is little.Ryan
I lost my wife because I wasn't man enough to put her needs ahead of mine. Don't make the same mistake.Slaugher
