Stiles-

"Derek, Derek- C'mon, they left already, you need to calm down…"

I'm holding the slowly shifting face of a werewolf in my hand. I have to calm him down before he completely shifts and storms out of here.

Pulling his face to mine, my lips find his in the darkness. His growing hair scratches my face but I deepen the kiss, wrapping my arms around his neck and pulling him closer. Suddenly, a sharp pain invades my hip as his elongating claws puncture my skin. I let out a cry of shock and pull away, putting a hand to my side and pulling it up covered in blood.

Derek sees my blood and instantly starts shifting back to human, worry and anger at himself sketched all over his face.

"Fuck… Stiles, I'm sorry. I'm so sorry."

He looks at me with fear on his face as I examine my bloodied hand. "Come on, let me treat that."

I oblige and carefully let him examine my side, seeing as I feel like I'm about to faint from the sight of all the blood and couldn't do anything on my own right now. He stands up and offers me his (now human) hand and I accidently take it with my bloody one. I feel Derek's arms catch me before I hit the ground in my last moment of consciousness before I pass out.

When I open my eyes, I'm lying on the bed with a bright light shining down onto my midsection. I squint my eyes to adjust them to the light and groggily look down at Derek applying rubbing alcohol to his claw marks.

"Derek… what happened?"

He replies without looking up from his work.

"I lost my control and hurt you Stiles… I got so worked up about whoever was here that I shifted and clawed you. I'm so sorry."

His voice is almost a whisper and I see tears forming in his eyes.

"Derek, it's okay. Seriously, it was my fault for getting so close to you during a shift. It's not your fault…"

I see his bottom lip start to quiver as his hands begin to shake. I reach down and hold his hands in mine, steadying them as I ignore the jolt of pain in my side.

"Derek…"

He slips his hands from mine and goes back to his work on my hip. I stroke his face with my hand, trying to rid him of the worry plastered across it. He reaches behind my leg for something and I lean my head back on the pillow as he gingerly applies butterfly bandages across each puncture and covers the area with some gauze. As soon as he's done I sit up and grab his face. My hip starts throbbing but I don't care.

"Derek, look at me."

He shifts his eyes into mine and I pull him forward, connecting our lips before he can say anything. I hold him there while he starts kissing me back way more tenderly than I thought was possible for him. The pain is gone as he wraps his arms around my midsection to take it himself and I pull him backwards on to the bed, rolling onto my uninjured side and wrapping myself up into his chest and arms. I lace my fingers through his.

"This. Is. Not. Your. Fault." I accentuate each word with a kiss on his lips. "I. Love. You."

He runs a hand through my hair and down my cheek as he places a kiss on my temple. "I love you too Stiles. But I'm so scared… scared I might hurt you. I can't live with myself if that happens. And it could happen. Very easily." He squeezes me tighter and I accidently gasp. Shit.

He's off of me in a second and sitting on the edge of the bed with his head in his hands. Real fucking smooth Stiles.

Derek looks back at me with nothing but anger on his face. Anger at himself, at the Alphas, at whoever was in the loft. His eyes flash red as he gets up and walks out of the room, shutting the door behind him as I lay in the bed confused and upset.

I sit up slowly to avoid a head rush and walk over to the bathroom while I go over what I'm going to say to him in my head. I turn on the light and examine myself in the mirror, gasping when I peel the gauze off slightly and see the actual damage he inflicted on my side.

Five angry, inch-long gashes decorate the area right over my hipbone but directly under my waist. I trace a finger above one and wince at the residual pain burning in my skin from the puncture underneath. Blood slowly starts seeping out again as I reapply the bandage and gently pull one of Derek's shirts on.

After pausing by the bed to collect myself, I walk over to the bedroom door and open it, preparing to talk him out of his mental state when I see him sniffing everything in the living room piece by piece, searching for the unfamiliar scent of the intruder.

I let out a small laugh at how funny he looks. I should be used to all things lycanthropic by now, but seeing a grown man sniffing around a room is still pretty funny. I lean against the wall and watch as he walks from wall to wall, attempting to follow the path of a scent through the room.

He stops as he reaches the edge of the couch nearest to the bedroom and myself. I see him rip off the top cushion and hold it to his nose, no doubt trying to get a better smell before he suddenly drops it to the floor and looks right at me.

"Stiles. Run. NOW."

His eyes start glowing red as I watch his claws begin to elongate and dig into the couch as he tries to restrain himself from shifting.

"What's happening? Why are you shifting?!"

He looks over and I watch his canines inch their way over his bottom lip.

"Get… to Scott… now…"

"But-"

"GO!"

He lets out a loud growl as his transformation completes and I run out the door and to my Jeep, smacking my head on the door before getting in and driving 30 miles over the speed limit until I pull into Scott's driveway. I try and pull out my spare key to his house but my hands are shaking too much, so I just start knocking until finally Scott opens the door.

"Stiles, what the hell! It's 3:46 in the morni-"

He stops when he sees the look on my face, the way I'm shaking.

"What happened?!"

I wait until we get into his room to explain and Isaac joins us from the guest bedroom down the hall.

"Someone came in the loft… red eyes… left before I realized it wasn't Derek…" I pant as I try and tell them what happened as quickly as possible. "Derek was checking the apartment for the scent…" I stop and take a few deep breaths to try and rein in my emotions before panic can take over. "He picked up a pillow and sniffed hard into it, but then he dropped it and told me to run and find you…. as he started to shift."

I pause and rub my hands up and down my arms, feeling goosebumps at the memory of the way he had said it. I had never heard him be that serious before towards me. Ever. "What the hell happened to him?"

I look up at them for an answer, but they aren't looking at me anymore. They're looking directly behind me, at Scott's window with a look of fear on their faces. I turn around slowly and look at the two glowing red eyes staring at me through the window, all traces of Derek's human side gone from this animal that pulls back his fist and punches through the glass.
