Adam was watching what was going on in the room. He was hesitating majorly on whether he should be doing what he was going to do. He was a scaredy cat though, so who knows what he may be thinking. When he saw Oscar's back turned, he gulped, slowly lifting his shirt to take the Stake out from his pocket. He didn't know the damage affect it would have on a human, but it was worth to try. Just think of it as a Crucifixion, just through the heart. He crouched a bit, coming towards Oscar from behind. He within sight that Katherine could see him, but not Oscar. He hesitated, taking a deep breath, he jumped up, wrapping his left arm around Oscar's neck in a choke hold. Then he drove the stake right through his back, penetrating his heart. One could say, his first time murdering someone, and to save another person. He was in a place where he knew Oscar could not reach him, and a place where the stake could not be pulled out. He just hoped it was enough to help Katherine.
