CASTLE Review: The Great Castle Divide

So what happens now?

I know a lot of fans are stunned at these developments, despite teases over the summer. But there are some things to keep in mind:

Remember the other Captain Beckett? The one from a world where she never met Castle? Remember when she was just going to take the easy solve on the case, let the deeper untouchable culprit off, and call it a win? Remember how Castle said the woman he knew and loved would never accept that?

Remember after Beckett was was shot, and he told Alexis he had to see it through, because everything that had happened was because of him, and he owed her?

Five people died because Kate Beckett was so obsessed with getting Bracken, she abused her position. She isn’t the kind of person who can just let that go. It happened because of her, and she owes them. And she can’t just let their killer walk free for her own safety. If she did, she wouldn’t be the Beckett we, and Castle, love. But she’s not going to let that put Castle at risk. She’s lost her family once, and she’s lost him.

Kate may have told Castle she was leaving to get her head together, but she’s going after the bad guys. Castle doesn’t know about Hyde not being the Bigger Boss or Rita. Kate wants to keep him out of it for his safety, because she loves him. She’s not ending the marriage, not at all. She’s doing this because separating herself from Castle for a while is the only way she knows to both do the right thing, and keep the people she loves safe.
