Retrovertigo.

His mind devolved into madness once more as the freezing air bounced from his pale white skin and back to the atmosphere around him. Science was one of the only subjects he bothered to retain information from, so he decided that instead of the air molecules absorbing his heat, they just left him alone. Just like everything else seemed to do now. His entire body felt stiff and warm like he was sitting on a bench on a lukewarm autumn day; except that he wasn't. Instead, he was walking for miles in the cold, following a set of tire tracks that might not even matter. Or at least, that's what Jonah would say. To him, these marks were the only possible option for where the van was. To where Jonah was. Adam always seemed to think in absolutes- Jonah actually bothered to fret over the details.

When Adam finally leaves the basement, his brain is a fog of what it used to be. But with the van- and Jonah- now on the line, he learns that his emotions aren't what he thought they were.
