Jack shivers and shakes his head quickly, "Don't get me stuck in here again! You deserved getting beat up, I don't care what you're doing! And Ms. Hodunk said it was fine." He might be twisting Moxxi's words just a smudge.

On the other hand, the talk of dimensions brings a quote to Jack's mind. I could explain the science that makes what you're doing impossible, but that would be like playing Mozart for a tree frog. His father told him that, in reference to getting close enough to kill him. But he succeeded there. Surely he can figure out some way to succeed here... that calms him down a little.
