Welcome to the Dark Side

Theo was sitting on his couch when he heard footsteps outside his door. He heard the person waiver by the door like they didn't know if they wanted to knock or not.

Since the war, Theo turned his life around. He stayed in Beacon Hills with an agreement with Argent to help him hunt down the hunters. The man and he made a decent pair; neither of them completely trusted the other, but they both respected each other in their own rights. Both believed in justice but also knew how to get their hands dirty. He rented out a small apartment on the edge of town, much better than living out of his truck. He was content; he met up with Liam, Mason, Corey, Nolan, and Alec once in a while. He was accepted in their little pack. Despite the occasional supernatural threat or hunters, they acted like normal teenagers. Theo liked it, having friends, doing some good in the world. With Scott, Stiles, and Lydia off at college, and Malia and Peter in France. Everyone else seemed to not mind having the chimera around.

He stared at the door, not knowing to get up or not when he smelled a very familiar scent except something was wrong. It smelled as if fear, anger, and anxiety were all mixed into one small body. Theo quickly stood up and opened the door, when he found a little beta collapsed at the door.

"Liam, what's wrong?" Theo pulled him inside, noticing the blood on his hands. "Are you hurt?"

Liam shook his head, "it's not mine."

Theo noticed his breathing was rapid, tears streaking down his face. Something happened he knew it.

"Liam, look at me; you have to tell me what happened," Theo tried to get him to speak. He was about ready to kill whoever did this to Liam. It was no secret that Theo cared about Liam, how much was up to debate, but he sacrificed himself way too many times for the beta with anger issues not to care.

Liam just stared down at his hands coated in blood. Theo grabbed his hand, "let's wash these at least."

"I can't," Liam pulled his hand away and stood up almost walking out the door.

"Liam, hey whatever you did you're still my best friend," Theo grabbed his arm pulling him back in.

"How do you I did something?"

"Liam, I know you," Theo stared into his eyes.

Liam nodded, leaning on Theo. He didn't know why he did. He just felt comfort from the chimera; that's why he ran to him first. He needed Theo; he figured out Theo was his anchor after Hayden left him. It was obvious even Mason and Corey pointed it out all the time. Theo was the only one that could calm him down at this point. He really wished he was with him an hour ago.
"Talk," Theo pulled him into his side. He felt the boy's body curve into his own. He enjoyed having the beta leaning against him. Liam just looked up at him, his eyes glowing a bright blue. Theo knew it why else the beta would come to him; he was the one with experience.

"First kill," Theo muttered, "guess you need my help explaining this to Scott."

"I didn't come to you because of that; I need you," Liam admitted.

Theo heard the yearning in the beta's voice; the way he grabbed Theo's hand. Theo realized he didn't just need Theo for his killing experience. He came to Theo because he chose to.

"I'm here," Theo wrapped his arm around him, "what happened?"

"My parents are dead," Liam said sadness overwhelming his voice. Theo could feel the boy physically tremor at those words; grief ripping through his body. He couldn't have wolfed out on his parents.

"I didn't kill them," Liam continued.

"I knew you didn't," Theo began rubbing his back, trying to calm him.
