Ethan froze for a moment at the thought of a blood sample. He hated needles, they hurt just as much as his venomous bite. Now he knew why he never went to the doctors, because of needles. "I- I don't know..." he said, feeling a bit uneasy. "I don't need anything to fight it back.. I just... want to know why it's happening is all..." he told them. Though the thoughts of a blood sample was making him light-headed. "I don't like... needles..." he said weakly before stumbling a bit, and passing out. Well, if they did get the blood sample, Ethan wouldn't feel it, but still, there was a reason why he hated doctors. It was the fact that they always wanted to draw blood from him. And he didn't like that, it was like taking things from him that he didn't want to have taken away. Even though it could be easily gained back through eating something. Course, Ethan was known to eat mice, like a snake would.
