Instead I think she might be some (un)friendly competition, professionally and maybe even personally, which is where Castle would come in. Though I think Castle has reached a point where he might do the whole Jordan Shaw thing, he might even get excited about a new detective and her possible hotness, but he won’t do anything about it because he loves Beckett. Unless Beckett does leave…but even then, I don’t think he’d move on from her fast at this point. I don’t even think he’d turn his back on her again if she went on another suicide mission like she did in “Always”, that’s how much I think he’s come to love her. And I still don’t think she will leave, but anything is possible. But then there’s the fact that I think Beckett is pregnant so if I’m right and she ends up having the baby, the new detective could be a temporary replacement?

It could go a lot of different ways, but I think I’ll like whatever the writers come up with because they’ll find a way to make it work.
