Charlie stays back, but she can still see the creature and that's what matters. She can see what she needs to, and therefor can still be useful. She can keep Bran safe, give him an advantage, maybe. And while her telekinesis wears her out, and her Snickers bar has fallen into a puddle of god knows what, she's going to do what she can.

Fire may not be the best bet, considering Bran was too close to the thing and Charlie didn't want to hurt him by accident, but she can move the creature. And that's what she does.

It's a focused telekinetic shove, just on the creature alone, and it gets flipped onto it's back.

And the curious thing here is it's own limbs just can't bend the right way needed to set it right side up, so it's going to flail and squirm and screech at the indignity of it, tail thumping uselessly on the ground. It's only a matter of time before it rights itself, but Charlie's keeping it pinned and looking kinda pale in the process.
