Scott's POV:

After what had happened at the loft I knew Stiles probably wanted to be alone but I also knew that Derek had followed him back to his place so I just wanted to make sure my best friend was alright, so I convinced Isaac that we needed to make a stop on the way home. As we neared the house we could both smell it. Blood. Stiles' blood. And a lot of it. We both shifted and began approaching the side of the house when we leapt up through the open window into Stiles' bedroom what we saw shocked us. Derek had Stiles pinned against the wall and he was suffocating him. Stiles had clearly already lost consciousness and had gone limp. Before either of us could move Derek released the grip he had on Stiles causing his body to fall to the floor. I growled. What had Derek done? He turned to face us, for the first time realizing that someone else was in the room. For a moment the room was quiet and was barely lit except for a bedside lamp and three sets of glowing werewolf eyes, one blue, one yellow and one red. "What have you done?" I growled moving towards Derek while Isaac raced to the prone body of Stiles lying motionless on the floor. Derek smirked at me and replied, "He deserved it. He wouldn't shut up. I had to show him who was boss." His reply left me almost speechless. This wasn't Derek. Something was seriously wrong and whatever it was had managed to escape the attention of the whole pack and now Stiles was paying the price. So I did the only thing I could think of at the time. Before he had a chance to react I attacked Derek, which in the small bedroom was no easy feat. I figured if I could hurt him or a break bone that this would trigger his healing and whatever was affecting him would hopefully be expelled from his system. Whatever was affecting him made him sluggish to my advance and allowed me to gain the upper hand quite quickly. Catching him off guard I wrestled him to the ground before managing to put him in a sort of arm bar before applying the necessary pressure to make his arm snap. The change was almost instantaneous. His face went blank for a moment like he was trying to work out where he was and then it was as if everything that had happened came flooding back. He pulled himself up with his good arm and looked towards where Isaac was cradling Stiles in his arms. "Isaac talk to me." I said as drew closer finally seeing the extent of the damage Derek had done to Stiles' body and it was not a pretty sight. "Scott he's breathing but barely. If we don't get him to a hospital and stop this bleeding he's not going to survive." Isaac was crying as he said this to me. Although he never really showed it I knew he had soft spot for Stiles. Stiles had helped him to deal with the panic attacks that he would sometimes get as a result of what his father had done to him and so Isaac was very grateful to him for that. I barely let him finish however before I pulled Stiles into my arms and ran towards Beacon Hills General Hospital, hoping that I wouldn't be too late to save my best friend.
