Is Roy high -- and if yes, then what is he on?

Feeling warm and enthralled by the movement of light, while the mind continues to race forward? Lucky bastard -- he's probably on Pyrholidon. It's tough to come by on the street.

Nope, still no clue. You obviously haven't been doing enough drugs lately.

Okay, he definitely is high. Whatever it is you've probably done it -- and many other things besides. But you can't cut through the jumble of sensations to get to the answer.
