"On your left! Left! No, Right!"

"Stiles, make up your mind, which way did he go?"

"I'm not sure, sniff around you're the werewolf!"

"Whatever, you go left, I'll go right."

Scott ran down the alleyway looking for a man that he and his pack had been trying to find for months. Currently, Stiles was driving his rusty old jeep and Scoot was sniffing the air, but they couldn't seem to find him. He had just been hanging around a gas station, but now seemed to have vanished.

Scotts phone started ringing, and he looked and saw that Derek was calling.

"Have you found him yet?"

"No, we lost him."

"How, you said you were following right after him!"

"I don't know, Stiles was-"

"Of course Stiles was doing something wrong, just look. He has to be there somewhere."

Just as Derek ended the call, Scott caught sight of a figure running across the top of an apartment building in front of him, and ran towards him.

When he caught up with him, he recognized the scent of the man that they were looking for, and yelled, "Hey! Wait!"

The man didn't stop, bus instead jumped across to the next building. As Scott chased him, he also noticed the scent of blood in the air though he wasn't sure if it was coming from the man himself, or from someone the man had hurt.

They kept running until there were no more buildings to jump onto, just empty lots and cars.

The man hesitated, not knowing what to do. He jumped off the roof and onto a fire escape, and then onto the street below. He kept running, and turned a corner, ducking into a not her alley.

Scott was following close behind, and heard tires screeching ahead of him.

As they entered the allye, Scott saw that it let out onto the next street, and that the man was about to escape. Just then, Stiles pulled in front of the alley, and jumped out of his jeep, holding a velvet bag. He began pouring th contents of the bag out in front of him, and the man who Scott was chasing stopped.

"It's Mountain Ash, you can't cross it." Stiles smirked at the man as Scott came up behind him, causing him to whip around to glare at him.

The man was wearing all black, and had the hood of his sweatshirt pulled over his face.

"Who are you, and why are you here?" Scott said, advancing on the stranger.

The man didn't say anything, but turned around, looking at the line of Mountain Ash.

Scott walked forward, grabbing his arm. "Hey-"

He was cut off as the man threw him back, growling and letting his hood fall to reveal his face. He looked angry, half-shifted, and had icy blue eyes that tore through Scott and glowed like the moon.

Scott stood up and winced, seeing that the man had sliced his chest with his claws. He closed his eyes for a second, and when he opened them the man was running over the Mountain Ash line.

"Scott!" Stiles ran over, quickly helping his friend stand.

"How did he get through that?" Scott said, wincing again.

"Well it wasn't really a circle, just a line."

Scott nodded and let Stiles help him to the jeep, and then drive him to see Dr. Deaton at his office cross town. He sent Derek a text telling him that the man got away, and Derek and Peter, along with Malia, Liam and Lydia were waiting for them when they arrived at the clinic.

"How could you let him get away?"

Derek growled, as Liam rushed forward to help Scott out of the car.

"Hey! He didn't just let him leave, we were trying to hold him, but he got mad and did this" Stiles said, pointing out Scott's injuries.

Derek rolled his eyes as Deaton came to the door, and then led the group to the back of the clinic where he cleaned and bandaged the cuts.

As he was attending to Scott, Deaton started questioning him. "So this was the same guy you guys saw last week right?"

"We think so, he was wearing the same hoodie, and looked the same as far as I could tell," Stiles answered, sitting on a counter beside Lydia.

"Yeah, he smelled the same too, and there was something else," Scott added, hopping off of the table as Deaton finished. "He smelled like blood."

"Do you think he killed someone else?" Liam said, concerned.

"I'm not sure but we need to stop him. He has hurt enough."

Across the room, Peter rolled his eyes. "Yeah, well you guys have been chasing him for weeks, and you only recently actually saw him. And when you did, you all got your assessment kicked. I've never seen a beta fight that well, so I don't know how he does."

Derek glared at him and grumbled,"He didn't fight that well, let's just find him." He then rolled the shoulder that the stranger had ripped out of its socket the last time they saw him, and Peter smirked.

"Sure, yeah, go ahead. Don't let me stop you from getting your selves decapitated, I don't really care."

"Yeah, we know you don't, crazy psychopath," Stiles mumbled.

"Guys, we still have to do something. This guy is hurting people, and if we don't stop him he's just going to keep killing. We have to do something." Scott said, stepping forward.

"Yeah, I agree. Let's stop him," Lydia responded, followed by Malia, "Yeah, let's kick some ass!"
