The thing about the lack of scars, the whole pinky- half of why he'd missed Arthur was those differences, the ways in which that body didn't resemble the one he'd been in last. But by now, he's already rationalized it: he hadn't had any body before he showed up here, so this place had given him one. And a tree-pinky and a look of starvation didn't match what this place wanted, how it wanted people to be.

But now that they're out here-

"Well, I'm furious with you too! You should have thrown that knife away the second Kayne gave it to you. He was fucking with you. He knew what you were going to do and I- I- I-"

And John, if he were inside, he'd be able to maintain his anger, keep it anger, but he's not. He's in the body of a teenage boy and that means his hormones are all over place and his emotions are supercharged even more than they usually are and that means the next words are sobbed out.

"Arthur, I'm so fucking glad you're alive. Fuck. Fuck."
