Well if he doesn't want to be yelled at for being a smartass then he should maybe, maybe consider not being a smartass. It's not difficult, this is a kidnapping, you just shut up and do what you're told, has he watched no movies?

In addition to the guns, he is also being handled way too casually, with two very large men carrying him by the elbows upstairs and a third large man ahead of them to make sure all's well.

He has done the shutting up, he's never been called a bad student. 

...Okay, lots of times, but no one once said he didn't know how to listen if his life- no, wait. 

Stiles fidgets excessively but doesn't resist or talk back. 

They reach upstairs and roughly push Stiles onto the ground.

Someone approaches the front door. 

The man they've been waiting for. 

That's not very nice. Could at least buy him dinner first.

He keeps quiet.

One of the large men upstairs sees the Sheriff from his vantage point.

"Yo boss. Smartass' daddy's here."

She nods minutely. 

"Invite him in. I think he'll be able to help us out." 

She walks down the stairs, ready to receive her guest. 

The three upstairs remain upstairs.

The seven downstairs stand at attention, two watching the backdoor, four watching the front door, and one flanking their boss.

One of the thugs watching the front door opens it slowly.

"I hope nobody cares that I brought a guest." 

He's holding an umbrella, and the umbrella opens...

The thugs are all suddenly very uncomfortable. "Boss," the one flanking the Coyote leans closer to whisper, "I think I know that guy."

Two of the other men standing closer together, converse, too: "Hey, haven't we seen that guy before?"

"Yeah, I think so, a coupla years back. What was his name...?"

"I told you to come alone," she says, speaking softly, smoothly, but with a hint of the same confusion her employees have. 

"I'm afraid I'm having trouble placing your face. Did we work together on a previous job? I hope I'm not stepping on anyone's toes." 

"Oh, I'm sure it'll come to you."

He reaches for something in his pocket. 

The armed men hesitate in raising their arms a bit. They shouldn't shoot him, should they, that'd be an asshole move—

He places a hand on his friend's arm and pulls out an unremarkable notebook.

Spiral-bound, but they won't get much of a chance to look at it before he closes it. 

It's high-pitched, approaching the edge of what he can hear, and it's louder than it has any right to be, and it's discordant, like drums crashing and wind whistling and guitar strings snapping under the pressure and a crack of thunder and he feels warm and tastes iron and he can't think about anything other than the pressure building in his head-

He really should have tested that earlier. 

Nail file in hand, he waves it. 

He shows them the light. 

Half the warehouse in one sweep, half in the other. 

All guns are dropped, and some of the thugs start screaming. A couple fall to their knees, hands trying to cover their ears and make that horrible noise stop oh my god—

And then they're down, one by one. The light reflects on them from the nail file and they don't even know what hit them.

The thugs upstairs start running back down to check on what's happening, leaving only one to keep an eye on Stiles.

They can go down as well.

Nail files are really quite useful, apparently. 

Hopefully Kaede and Yeong make a spectacular entrance, because he has to get the liability his friend out of harm's way.

He opens the notebook, and makes his way back the way they came.

The door at the back opens and, after verifying that the Coyote and her thugs seem to all be unconscious, Kaede steps through and makes his way towards the stairs.

Followed by his mother.

Stiles does not say any quippy one-liners, because if he's being rescued, getting shot would be a bad way to show gratitude. 

Also, he's on the edge of a panic attack and nothing funny is coming to mind here.

Alan starts the car, and waits. 

Kaede verifies that the thug near Stiles is down and approaches. "Stiles? Are you alright? Did the notebook—the noise—did you get hurt?"

"Nope, everything's swell, time to leave. I can freak out later." 

He...grabs Kaede's hand, apparently.

"Do we have a way out?"
