He'll hate himself later for how fast his brain makes the instant connections - Natalie talks to Misty about everything; he knows they have some kind of shared, undoubtedly traumatic history. Something that John apparently sees as relatable to their time in the pit. How they survived means--

"Jesus fucking Christ."

Alright, well, there's something fucking horrific they have in common that he really wishes he didn't have to know about. But his problem is still, now, that Natalie knowing it means, without a doubt in his mind, that Misty will inevitably hear of it. And he can't un-think the way it sends a repulsive chill to settle low in his stomach.

"No."

Fuck, he- he can't do this right now, he doesn't want to even think about this, let alone deal with it.

"...get out."

And he's going to grab John's mask to try and make him if he doesn't.
