Stiles stepped into the abandoned subway tracks and smiled at the pack.

"Stiles!"

Scott, Allison, Danny, and Isaac jumped up from where they were sitting, practically throwing themselves onto the poor teen. Stiles stumbled back, but Derek placed his hand on his back, keeping Stiles standing up. Stiles smiled and hugged the group back.

"Hey guys! Sorry I couldn't come for the pack meeting the other day."

Erica smirked as she stood up.

"Have fun spending the day with your dad?"

Stiles gave a tight smile as he scratched the back of his head.

"Sure did. We went fishing and then jogged around the lake."

Derek growled while Lydia sat up, head cocked to the side. Stiles' smile dropped from his face. Shit.

"You're lying"

Lydia accused Stiles.

Stiles gave a nervous laugh.

"N-no I'm not. What a-are you talking about?"

Derek growled as Scott, Allison, Danny, and Isaac backed up to look at Stiles.

"We can hear your heartbeat, Stiles. We can tell that you're lying."

Stiles backed up nervously. Derek stepped forward as he stepped back.

"Yesterday, you smelled like the hospital. Why were you at the hospital?"

Stiles' breath quickened as he backed up further, closer to the stairs.

"I-I. . . it's just. . ."

Stiles spun on his heel and raced up the stairs. The pack jumped forward to go after him, but Derek held up a hand, stopping them.

"No. Let him go calm down. He'll talk to us when he's ready."

Scott growled

"But he's my best friend. I can't just-"

"You can, and you will!"

Allison placed a calming hand on Scott's arm.

"He's right Scott. He needs time to cool down. He'll tell us what's going on when he's ready."

Jackson nodded and spoke up.

"Yeah, he's probably not even sick. For all we know, he could just be visiting someone."

Everyone knew it wasn't true. They had seen how pale and skinny the teenager had become.

Scott looked up the stairs at where Stiles had disappeared.

"I just hope that it's not. . ."

Scott trailed off as all the blood rushed from his face.

Erica frowned.

"Not what, McCall?"

Scott suddenly stumbled back and ran towards the trash bin in the corner. He leaned over it as he threw up. Everyone jumped to their feet, surprise and fear dancing through their minds. Allison ran over to Scott and started to rub his back.

"What is it Scott?"

"I-I can't believe I didn't notice it. I-I w-was there for the first time. A-and now h-he's"

Scott swallowed hard, trying to hold back his tears.

"Damn it, Scott! What is going on?"

Derek growled, a tinge of fear in the back of his mind. Scott looked up at the pack, a solemn expression on his face.

"I'm sorry. I-I can't tell you that."

"Why the hell not?"

"Because it's not my place to tell you!"

Everyone stood, stunned silent.

"I'm sorry, but the test results came back positive. You have APL Leukemia."

Stiles closed his eyes, dread enveloping his body. The doctor stood in front of Stiles and his dad, giving them the news.

"Your white blood cell count was over 100,000 and we need to start you on chemotherapy immediately. We will be inserting a central venous catheter with three ends into the right side of your chest. This will make it easier to administrate the drug without having to give you a million shots or keep you hooked up to an IV."

The doctor droned on with the facts, but Stiles had heard it all before. He knew what he was in for and he knew all the possible end results. Stiles felt numb for the rest of the day.

He was numb when they put him on an IV to hydrate him. He was numb when the scrubbed him down and prepped him for surgery.

He was numb when he was put under, and he was numb when he dreamed about a large black wolf.
