I'm gonna wait out this season until the mid-season break to see if there are any positive turn ups. The plot device seems tacked on, they're still working together, so it makes no difference. And she's not even going all in into this thing. Castle's stepmom implied that if she wanted to go all in, she'll have to give up her life like she did, and more or less go Jason Bourne. Which makes no sense at the moment since she just gave up (not really) on Castle by leaving the house, which is....nothing. She's STILL part of the precinct, she's still married to him, only difference is she lives separately. As if villains would care if that makes a difference. As long as he's still part of her life, he's still in "danger", and by her not being there in the frontline to protect him, won't he be in even more danger now since she's not there to keep an eye on him. The whole device of her needing-to-leave-him-but-not-really is so stupid.
