Flushed indeed. "Y-you...!" But he didn't sound too upset when Snake kissed him.

"You know what I think? Maybe it's got to do with how direct ya are. Like... when you wanna say something, you say it plain. That's not all that common, y'know." Especially not to a detective, who was quite used to people lying to him about all manner of things, large and small. Maybe years of living as a blind man had simply cut short Snake's tolerance for insincere surface pleasantries.
