=•Barry's pov•=

The guy held a Stiles off the ground. "Flash.... leave now and no one gets hurt" The guy tells me. Before I got to say anything I got shot, from behind. I couldn't move. "kenima venom.." I hear Rick smirk as we walk up from behind me with a gun. oozing with the green venom.

I watch as he hits Stiles with the venom and they carry him into the back of their pickup truck.

I looked around and saw Allison unconscious on the ground, Joe was nowhere to be seen...

=•Third Person•=

Stiles tried to move in the back of the pickup truck but the venom was still in his system and he was paralyzed. He let our a long and shaky sigh as he closed his eyes.

He was instantly woken up when he felt his body fall. His eyes snapped open just in time to see something blue coming closer as he fell...

water...

he splashed int the water and moments later he shifted into his merman form.

He started to breathe underwater and swim to the bottom, and realized he was in a tank. It was spacious but that walls are also a one-way mirror except for the floor which was covered in sand.

He signed as he sat on the bottom of the ocean.

Rick's POV

As I flipped through the pages of a file that wasjust handed to me I see something that catches my eyes. "So what's in the sand, it'll do this?" I ask with excitement. "Yes the chemical we Put in the sand will cause his scales to shed" The scientist says to me. "They'll be just the same as if we took them right off him" He assured me. "Perfect" I smirk as I turn to face the tank with a merman in

"So fish boy! Did you know that your scales are one of the rarest minerals to ever exist?" I ask him. "No.... So that's why I'm here?" He asks in a low voice. "Not exactly... That and the fact that you're the last merperson on earth, and if we want to eliminate the mermaids then we'd need to get rid of you" I explain to him.

Third person
Stiles watched as Rick flipped through a book with pictures of every single supernatural creature they knew leading all back to the beginning.

"Are you trying to eliminate supernatural creatures?" Stiles asks him with concern.
"We want to, but so far the only ones we've found are in beacon hills, we thought why not start off easy and kill the species with the smallest population, so merpeople we started hunting since there's only you left it was perfect" Rick explains to Stiles.

Stiles made his hand into a fist and smashed it against the mirror glass wall he's trapped in.

"Try as hard as you want l, you won't get out" He says to Stiles

"What makes you say that?" Stiles huffs. "Because that glass is special, it's fused with mountain ash" Rick smirks at Stiles.

Back at Barry's house

Allison, Barry, and Joe all sat around the kitchen table as they tried to make a plan on how to get to Stiles. "we don't even know where he is" Allison tells them. Barry looks away for a moment. "Come with me. "Joe we'll be back, hopefully with Stiles" Barry tells Joe before he grabs Allison's hand and zooms off. 

He takes her back to his lab. 

"Okay, so I think I might be able to track where he is" Barry says as he starts speed typu=ing in one if the computers. 

"How can you find him?" Allison asks Barry as she looks over his shoulder, trying to see the screen. "Each supernatural creature lets off a special frequency, I just need to track it" Barry informs Allison. 

"Here... It's an abandoned where house" Barry says to me as he takes my hand and we zoom to that location. 

When we stop behind the building Allison asks. "We need a plan of attack". 

"If we can find a way in without them seeing we can try to locate where they're hiding Stiles, but whatever you do.... Don't get paralyzed" Barry says to Allison as they start looking for an entrance. 

Barry found a door, he ran so fast he went through the wall, then unlocked her door from the inside. "Let's go" Allison says as she catches Stile's sent. She signals to Barry to follow her as she slowly follows the sent. 

I followed the sent all the way to a metal locked door. "It's in here" She says as she reaches out to the door, but her hand stops. "Mountain ash..." She mumbles under her breath. "What?" Barry asks in confusion. "It's an ash that keeps all supernatural creatures out, and in" Allison tells Barry as he touches the ash but it's the same result. "it must effect power humans as well" Barry says as he stands up.

Stiles sat at the bottom of his tank, as a light pain formed in his tail... 

he knew this was the stuff and is made out of, the stuff that will make his sclaes fall off. It's a painfule process, when every last scale is off it will rid him of his powers as well. 

yet all Stiles could do was sit there... and wait
