"Elena..." David seems to catch himself and sighs as he glances about, finally starting to recognize where they are. "Doctor Marks. She proposed a theory that, because I wouldn't kill, the creature wouldn't kill. There was a fire at the lab, I -changed-, and when I came around we were clear of the building. There wasn't a mark on her that the creature could have made."

That had been a private horror for him, and he'd had many instances where he feared the monster within him had finally gone too far. In fact he had nightmares about it, but looking back at years of episodes, no one had actually died because of him. People had been hurt, and that was difficult to shoulder, but the weight of a life in his hands he knew would break him. The false belief that he'd killed someone in the past had already come close to making him take desperate action.

David goes quiet as he follows Matt up the fire escape, trying his best to keep his footfalls light. Lacking shoes, he finds it necessary just to keep the metal grating from making the healing skin on his feet hurt more. Now that the adrenaline had thoroughly worn off, his whole body was starting to ache from the fire. Aloe will go a long way to helping him relax tonight.
