"Scott, calm down. Everything's going to be fine. We'll find them, and we'll make sure they can do whatever they want to do."

"They... don't want things the way humans do, they have opinions and personalities, they don't feel pain the way humans do, they know what's happening to them. And it may not be fine, the cards released will bring catastrophe to the world."

"Right, next time lead with that?"

"Okay. What do I have to do to find the others? How can I be sure that Windy won't blow them away again after I find them? How can I stop them from wreaking havoc?"

"I will need to make you a cardcaptor, and you will be entrusted with the job of finding them, capturing them, and keeping them from destroying the world."

"What do I need to do."

"Slow your roll there, buddy. 'Entrust'? Is there a contract here, can we please see the terms?"

"...terms?"

"Stiles, I'll take this one."

"What do I have to do, if I become a cardcaptor?"

"You have to capture the cards, take care of them, learn how to use them, protect them, and treat them with respect."

"Deal. How do I start?"

The book stands up again and a little point of blue light appears within its lock, and floats towards Scott until it's between Cerberus and him. It grows, and a small key appears inside it. "Key of the Seal, there is someone wishing for a contract with you," he starts intoning.

"What should I say?"

He reaches for it.

Wind! Lots of wind, pushing him back and preventing him from touching the key. "A boy! His name is Scott. Oh, Key, grant him the power. RELEASE!"

His surroundings are replaced by a black void, the only things present being himself, Cerberus, the Key, and a glowing circle much like the one on the back of the Clow Cards where the "ground" should be. Stiles is nowhere to be seen.

He reaches for the Key.

As he does, the key grows and changes shape, turning into a staff. The closer he is to it, the stronger the wind pushing against him. "Now, Scott! Grab it!"

...

Stiles is going to tease him mercilessly about this.

He takes the staff.

The staff finishes growing and Cerberus declares: "That's it! The birth of a cardcaptor!"

The wind subsides and disappears, his surroundings appear again, and as far as Stiles is aware no time at all has passed but Scott is suddenly holding a very pink staff.

Stiles does not laugh.

There might be a little sporfle, but he exhibits incredible self-restraint.

Truly heroic.

"Okay, what's next? How will I find the cards before they do any damage?"

"Scott, dinner!"

"Stiles-"

"I know the drill. I interrogate the bear and if Mama Blackstock comes up, we hide in the closet. Bring me something."
