Pyro controls flames, but can be burned. Scorch makes and controls flames and can't (well, she's been burned a little... by nuclear level explosions). I also think she can go a lot hotter.
It's a flame control tug-of-war that she can't lose. She'll just keep making it hotter and pushing it back toward Pyro.
Pyro is resistant to ANY flame that he sees or manipulates. But I don't think hes ever resisted a nuclear level explosion. Though he definately has better control IMO
He avoids being burned by manipulating it away from doing so.
Scorch also has very high-level flame control, in addition to producing it, unlike Torch in the other thread. So it's partially a matter of whether she can overwhelm his manipulation, power vs power. If her high overall power levels mean she can, then she wins quickly, if it's not enough, then it's a matter of endurance, keeping at it until he tires out.
She can also teleport, so there's 'porting and getting him by surprise.
This is how Pyro works, if he makes a jet of flame, thenblasts his arm, he won't get hurt, because he's manipulating that flame. But if someone like Fire or Torch did the same thing, he would have 3rd degrees.
