He is, he can't even deny it. Jesse's just glad Pinkman doesn't see it.

There's a look of relief from Jesse, though, when Pinkman says he isn't going to kill anybody. It's just - they're all probably going to die here, they're going to be fucked with further, he's sure. They need to be in this together. And he'd say as much, if he wasn't afraid he'd be made fun of. Normally he wouldn't care, but today, he's wary of it, still twisting at his hands.

"... Okay," Jesse says, looking at Pinkman. "Thanks." For everything - for wanting to stand up for him. "R'you okay? After - the gun." Because you hate them. He listens!
