TVLine have been talking to Castle showrunner Andrew Marlowe about tonight's episode and a hint of what's to come in the season finale. Here's what he had to say.
...As part of tonight’s encounter with the undead, “Castle has to confront his own behavior… and decide whether he can go on like this, if that’s the person he wants to be.”
First and foremost, the out-there installment is a “really fun, rompy episode,” Marlowe says — and therein lies the catalyst for the showing of cards (and possible revealing of anything else!) that takes place in next Monday’s season finale.
“It pushes Beckett and Castle to this place where, despite themselves and despite how they’re feeling about each other, they recapture a lot of fun of their relationship — and they have to deal with being confronted with that,” says the scribe. “It gets them each to a point where they start to recognize where they are in each other’s universe.”
And then…? “And then when we get to the finale, we turn things on their head — a couple of times — to get to where we ultimately end up.”
