I hated that this wasn’t in the episode. This scene would have made Kate’s approach to the job and not telling Castle and all of that make so much more sense.
You know, looking back and comparing season 6 to season 5, it’s obvious that in season 5 Kate was insecure about her relationship with Castle. I mean,I knew it, since she voiced it to him once or twice, worrying that the fact that they worked together or that they were from different worlds would affect their relationship. But it wasn’t until I saw season 6 and how carefree and relaxed Kate is in her relationship then that I realized how much she wasn’t in season 5.
In season 5 you can tell that they’re finding their way in the relationship and Kate especially, I think, is still constantly worried that they won’t last or that Castle might not be interested in a lasting relationship. And is therefore afraid to get too comfortable in the relationship.
It’s funny because while this is the one relationship where she’s in it with both feet and arms and everything, I think she’s bracing for the impact of a break up in case Castle possibly has one foot out the door. Which is kind of confirmed when her mind immediately goes to a break up when Castle’s trying to propose and she’s not even surprised that he’d want to break up with her.
The writers and actors did try to convey that, but comparing their relationship in season 5 to season 6, all of it really dawns on you (or at least me).
But this scene really does drive all that home before season 6. It kind of connects the dots between all those earlier moments where Kate questions their relationship and doesn’t trust it or how much Castle loves who she is enough to be completely honest with him nor does she give him the chance to be completely honest with her about what she really wants to know not willing to ask the questions, too afraid of the answers she might get.
