Isaac & Tommy
It was like he was in high school all over again, unaware of and unable to control his powers - after he vaporized the building, Tommy had been sent off to the worst juvie prison he'd ever been in. Where he was treated like a weapon. That all meant he was less than thrilled about becoming nothing more than a blur of rapidly-moving cells, destructive and violent, but his emotions were on a spiral out of control and, like most mutants, that often meant the powers went wonky too.

"I don't...I can't see you, but I'm about to make a crater, that's where I am," and he attempted to use that as a landmark when he ran up the next tree so fast it blurred in and out of focus and then there was a boom - leaving nothing left except a smoking hole in the ground, not even the roots having survived being vaporized too. "I'll try to follow your voice - " It didn't sound like Isaac would be getting up to come to Tommy.
