[Sonic's shaking. He's not entirely sure why, but he's never been particularly good at hiding his emotions, and now's no exception. If anything, Sonic seems angry, an emotion that's almost foreign on him, and while it's weak, Sonic manages to raise his head up getting right into Metal's business in kind.]

You aren't--you aren't either, you big metal lughead!?

[Sonic attempts to rise more, with only a painful wince forcing him back down, but his own look doesn't abate even slightly.]

Look, I thought I could take it! I know you're more durable! But at least if I got hurt, I could get fixed up nice and easy by the people here!

What if that thing managed to land a clean blow on you, huh?! Eggman ain't here to repair you if you go and kick the bucket!
