I love how serious he is when he asks her. That’s always been something she’s wondered about him—can he be serious when he needs to be, when she needs him to be? But of course we all know that he’s never more serious than when it comes to how much he loves her. There’s no joking, no smirk—just the earnest sincerity of a man who knows what he wants and desperately needs her to know how serious he is about this, about her, about them. Richard Castle isn’t scared of much, but he’s terrified of losing her—not to a new job or a new city, but to her own fears an insecurities about him. So he puts it all on the line, he takes the next leap forward and hopes to God she’s going to follow him. Because he’s ready—they’re ready. They’ve been friends for five years, learning everything there is to know about one another, breaking down walls and facing down death and falling in love. “Always” has a new meaning now, but that promise of forever has been there for so long between them—and that’s why this proposal felt so earned, so real, and so right.
