If he waves his wand does it manage to get away? 

"Erase, return to your power confined, Erase!"

Nothing happens.

He meditates, then, because he has so much time to save his friend. 

Half a mile that way.

"This way," and he Flies, leaving Victoria behind. 

—she follows, then.

And once he's near enough to it, he touches down.

Staff, meet...card?

"Erase, return to your power confined."

Nope! That way instead. Closer than half a mile, thankfully.

He can fly so fast. Watch him go.

Now?

It works!

Great. 

"Erase, return the things that you took, release!"

A car! Another three cars! A tree! A house! Stiles!

Stiles is very hugged.

"Um. Sorry."

"It's okay, you're okay."

"I feel like I wasn't very useful," she sighs. "This was surprisingly easy. Hey, Stiles."

He is very hugged.

"I'm okay, Scotty. Not existing sucks but in the way sleep sucks; I didn't really notice during."

"Very comforting, really. As long as you're okay."

"Not much worse than the time loop. Speaking of, should we maybe fix that?"

"Right. We had a... sort of plan. Which we'd enact right after midnight."

"Right. I'll explain everything to you tomorrow, I promise."

"Okay. Did we decide if things survive the loop, because I kind of want to record all this heroic rescue stuff for later."

"Touching. Shall I walk home, Scott?"

"No, sorry. Stiles, stay with Sadde."

"They don't survive the loop," she tells Stiles.
