The light of the real world filters back to his consciousness when he opens his eyes. He could, right now, probably tell where whatever-it-was was, but the way it was moving while he was meditating, it will probably be somewhere else by the time he catches up with it.

"I need to get the cards. Watch to make sure it doesn't do much damage."

He hops to it.

Stiles...knows there's a card.

Is there some kind of assorted havoc to see if he wanders the halls, glaring at anyone who questions his right to be there?

He might catch some other people with missing belongings, as well as some who have found theirs in bizarre places (like two floors down or under a locker).

There's some kind of thief on the loose, from a rival school, who wants to distract everyone before the big game. 

He spreads this rumor around to the best of his ability, and waits for Scott to come back. 

He ends up going to his next class, after stopping by the nurse to mention Scott is having a medical emergency. It's kind of true. 

Scott catches Stiles in the hall afterwards.

"I have them. Guard me while I meditate?"

Sigh.

Meditate.

Before he gets the fuzzy, he notices two things:

One, the cards have existences, they're entities, drawing the (metaphorical) eye, complex beings of pure magic.

Two, it appears his backpack is now glowing to his (metaphorical) eye.

He doesn't drop the meditation this time.

He keeps going.

Eventually he finds the skipping, zipping card, which seems to still be in the building, one floor down.

Trying to follow it pulls him back out.

"Stiles, it's downstairs."

And they run downstairs.

Scott can see it!

Stiles cannot.

It's a girl in a traditional Chinese outfit, jumping this way and that. She sees Scott, smiles, and jumps through a wall into a classroom.

"The Key which hides the powers of the Dark, show your true powers before me. I, Scott, command you under our contract. Release!'"

Staff!

(There are, however, students inside the classroom. Having class.)

They can't see the staff, right? 

Just him being weird. 

Well unless he's hiding it somewhere they can see it, just like Stiles did.

Good thing he didn't run in there without planning. Just summoned a magical item without planning. 

He stands outside, looking for somewhere convenient where no one can see him waving his magic stick around while he calls Windy.

It's an empty hallway between classrooms with lockers and windows into the classrooms. Good luck to him.

...

Yeah, he's doing it. 

He's not exactly sure what to do, but might as well listen to Kero.

"Windy, please surround the card and hold it."

The card doesn't do anything.

Kero's head pops out of Scott's bag. "That's not how you use a card!"

This is an utter trainwreck. 

"How do I use a card?"

"You have to throw it in front of you and then tap it with the tip of your staff and say its name. If you ask it something it'll do that."

Right. 

He throws the card. He taps the card. 

"Windy, please surround the card and hold it still!"

The card glows and dissolves, taking the form of a ghostly woman, who then proceeds to open the door into the classroom quite violently and create not a little chaos trying to grab the card there.

Except the card slips through the floor before she reaches it.
