"Sure, the more the merrier."

"We understand you have a plan. Alistair has explained the details, and I'll be taking his place."

"His place? Makes sense, I suppose."

"Okay. Are you using the Jump?"

"Sadde has more experience using the cards than I do, I'm sure she can take it."

"Sure, can do."

"Scott, do you mind if I ride along with you?"

"No, that's fine. Let's go."

The staff can support their weight, right?

Yup.

"Jump!" The card glows and two small wings appear on either side of each of her feet.

So he and Alistair's mother ride on his pink magic wand into battle. 

She jumps after them, not really bothering to keep out of sight since everyone's memories are going to be erased anyway. She has a moment of wishing the Argents' memories would, too, and then remembers that's a horrible thing to wish for.

The Erase is in a different part of town than before, vanishing cars again.

They arrive.

"Have you considered that capturing it now will be completely useless? It's possible this should wait until after midnight."

"We're not waiting, it Erased Stiles." 

"Yeah, the point here is to not let twenty-four hours elapse."

Lookit that car, disappearing much faster than yesterday.

Time to use their only strategy.

"Maze, make a path to the Erase, release!"

...nothing happens.

Can he do "where that car was"?

Yep!

So he does. A path for him and Mrs. Argent and Sadde, to where the car was.

It's longer than it should be, but entirely in non-Euclidean pockets of space, completely undetectable to the Erase.

And can he sense the Erase from inside, maybe? Please?

Nope!

They follow the path. 

There's the spot where the car used to be.

"Well, Mr. McCall? Capturing cards is your comparative advantage, I'm told."
