Only Say My Name

"Derek?"

Stiles crept through the musty house as he called out Derek's name.

"Hello? Anyone there?"

He turned down the hallway to what he presumed to be Derek's room. First door on the right, that's what Isaac had said.

Stiles breathed in as he put his hand on the handle, gently turning it. The door creaked as he pushed inwards, revealing quite a shocking sight. Stiles was so stunned, he just let the door drift slowly inwards, creaking as it went. He stood completely still, but inside his mind was running a mile a minute.

Oh shit.

Oh shit oh shit oh Shiiiit.

Stiles was panicking. Derek Hale was... Crying. This has to be unusual, right? Big, badass werewolves don't spend their spare time crying, right? Especially not Derek Hale, the biggest, badassiest werewolf around. Stiles was obviously not alone in this viewpoint, right?

Well, maybe they did. After all, werewolves were human too. Wait...

"Stiles?"

Derek turned around from where he had been sitting, interrupting Stiles's train of thought, and faced the teen, who was currently attempting to lean nonchalantly against the doorframe.

"Yeah?"

"What the hell are you doing in my house?"

Derek stood up and turned around completely, eyes flashing red as he faced Stiles.

"Well, you see, Allison told Scott that her dad was having trouble with this... Thing, and that they needed your help with whatever it was and then Scott came to me because... Actually I don't know and then we went to Isaac, but Isaac was busy, so he just told us where your room was and then because Scott was being a scaredy cat and wouldn't come inside then I said that I would go so long story short we kind of need your help."

"And you couldn't have called?"

"Well, you're actually pretty bad at the whole answering the phone thing and it seemed kind of urgent so we just decided that we would go to your house. Well, we being me. And sort of Scott."

Derek took a step forward.

"Please don't kill me!" Stiles yelped, whipping his arms up to shield his head.

There was a silence for a moment, then Derek spoke softly.

"I'm not gonna kill you, Stiles."

Sties lowered his arms and slowly straightened out.

Derek was sitting on the bed, staring down at his clawed hands with a mixture of regret and sadness. He blinked furiously as they shrunk back into his skin, seeming to fight back tears.

Stiles moved forwards, towards the bed, and sat down next to Derek.

"Hey," he all but whispered. "You okay?"

At this, Derek looked up at Stiles. He seemed positively broken, without his hard shell of an exterior that he wore around the pack. Stiles could see the sadness, the pain, the regret, plainly etched across his usually mask-like face. Water gathered in his hazel eyes, threatening to spill over.

He sighed.

"I honestly don't know."
