"I'm a bit confused as to how Ultear is suppose to "throw" the Sky Sisters out"

Pretty easily: She just has to stop blocking Dimaria from freezing them, like she did with Carla after she was hit.

But I doubt it'd be as easy as just unfreezing some other people and everything's good... for one thing those people are at least a few minutes' walks away. Dimaria could easily kill the Sky Sisters if you give her five seconds time, so waiting for minutes is out of the question.

Now Ultear could theoretically unfreeze the other people while keeping the Sky Sister unfrozen too until the others arive at the scene, but it looks like it's already very taxing for Ultear to keep just the two girls and cat moving, making it unlikely that she can get others involved and keep the effect going long enough for them to get to her and the time they'd need to defeat Dimaria.

It's easy to say "just pick someone else", but to put it into practice is quite a different thing.
