Peter does things because he can, because technology is just about the only asset he has on board the ship, and while Jack may be behind everyone else as far as that aspect goes, Peter is behind everyone else in terms of crucial knowledge. It's a trivial thing really, and not everyone may pick up on it, but Peter does and it kinda stings every once in a while when he tries to think too hard.

He looks up from his tinkering, at Jack's face, raises an eyebrow, because really, Peter kinda expected everyone to be familiar with some of the stuff on board. "Yeah? I guess?" Peter wrenches out a wire by accident as he mimics the gesture in return, completely caught off guard by Jack's presence.

"Not entirely sure what you mean, but yeah I kinda like fixing stuff, I mean, if it needs fixing." He rambles off more than he should, the screen going black and Peter's well laid plans completely falling apart in Jack's presence.

"Or. Well, I guess that needs to be fixed now."
