[Rock looks down at himself and frowns. That's a pretty good question. He hadn't really thought about what would happen after he'd saved his brothers. It wasn't like he could just go back to being a lab assistant now, right?]

... Dr. Wily got away, and there were those other robots he built. And even without all that, it's a bit too late to turn back now. I don't think I'd be able to just go back to only helping out in the hanger or Dr. Light's lab if I've got the power to help out in other ways.
