[Here's a short blond kid wandering rather stiffly around campus, pestering anyone who looks even slightly engineering-minded:]
Uh, 'scuse me. You know if there're any mechanics around here? Or if you are one, could you do me a favour? I'm not - well, I guess I am low on money now... but I'll work something out.
[Because if there's one thing more annoying than being unexpectedly and unwillingly propelled to a parallel world, it's being unexpectedly propelled to a parallel world where your arm won't stay on properly. Ed can in fact speak from experience since both have happened to him in the past day or so, and he's really pissed off about it. More than usual, even.
He mentally takes stock yet again, in the hope that his situation will make a little more sense the fifth or sixth time through. So... he woke up, definitely not dead. That's a bad start. And then he went and enrolled in the first group he bumped into that remotely resembled a military, which just goes to show he hasn't learned anything. Shortly after that, after they left him to his own devices for the rest of the day, was when his arm fell off. What was it doing here in the first place, anyway? And his leg? He supposes it's better than not having them at all, but...
Nope, no more sense. Oh well. Maybe if he walks around long enough and bugs enough people, someone will take pity on him. And it serves the additional purpose of familiarising himself with these new surroundings, he tells himself, because he hates feeling as useless as this.]
