Desmond was so tired... He looked up and saw a girl he didn't know. Must be that newcomer Nurse Phil was talking about. Heh, she was kind of cute... What's with all the girls here being cute, in their own way? He looked at his hands and realized they were leaking dark energy again, smoke seeming to come from them. He knew he wasn't about to blow up again, so it probably meant he needed to get a grip. But the more he tried to focus the more darkness seemed to pour from his hands. And yet... as more and more was released, he started feeling... better...
It was the goddamn nurses. This realization hit him like a freight train. He was still recovering even when he was trying to go after Nurse Phil, and he'd been draining dark energy from the area, including directly from the nurses. The dark energy he got from the nurses... it was tainted. It made him sick to his stomach, his skin was crawling. He fell to the ground and felt the bile welling up, he couldn't hold it in and he began heaving onto the floor. But it wasn't bile. What came out of him was a black liquid, that spewed from him with power, and upon contact with the floor almost immediately evaporated into its gaseous form.
When it was done the boy sat there, shaking, but feeling so much better. His shaking eventually stopped and he stood up, hoping that new girl hadn't had to witness all of that. He didn't want to creep her out or anything... He shook his head and turned to see if she HAD watched all of that, and wiped away some remaining black liquid on his chin, it evaporating when he flicked it onto the floor.
