Last we saw Kate Beckett she was taking more of her things from the loft she shares with her husband…but leaving him her shirt?

What did it all mean? Here’s the inside scoop from Castle co-showrunners Alexi Hawley and Terrence Paul Winter.

“Part of [Rick’s frustration] is that he doesn’t quite understand exactly what’s going on with her,” said Hawley.

“His questions about what’s really going on are what’s ultimately driving us to the end of the fall finale,” Hawley notes. “But I do think that even though she was talking about moving out and she got her stuff, what happened with The Nose and everything definitely relieved him a bit.”

Co-showrunner Terence Paul Winter reminds fans that, “The reason why she created this separation, again, is out of love,” but “She wants him to remember her, so yes, she knows what she’s doing.”

As for Castle Season 8 Episode 6, “Cool Boys” where Castle is paired up once again with Detective Ethan Slaughter, Hawley said, “He does start off the episode going, ‘It’s getting a little old,’ because he does in private struggle with it."

"So what we really tried to do with him and Detective Slaughter was have a bit of the ‘guy conversation’ about ‘What’s happening with your wife?’ But also really flip that guy perspective on its head, in the same way that we try to flip the Slaughter character on its head a bit.

“They definitely talk about it,” Hawley continues, “but again, it ends up being a positive conversation.”

Do you think the next episodes leading up to the big fall finale titled “Mr & Mrs Castle” on November 23rd can bring the Caskett magic back?
