"You feel cold," he replies, doubting very much that his own temperature has changed, but realizing that Charlie's has. A direct effect of the bite, maybe, or the resulting tiredness and confusion -- he's simply too close to unconsciousness to be seized by the same fixation for shiny things and shiny people that he was before.

In that way, Meyer thinks, maybe this did help. Maybe. He knows it helped him, because for the first time in two days, he doesn't feel driven to distraction by hunger and thirst. He feels calmer, more like himself. If there's some way he can believe this helped Charlie, too, he'll grab onto it and believe it as best he can; he can't let himself think that hurting Charlie like this was for nothing.
