I tried my damndest to track him (Or this person who shares his name) down during the con, but not once did I catch sight of that nametag, although I saw several people who fit his description.
Just thought this was a tidbit that all the Kevin Caldwell obsessed people might find interesting.
If it really was him, I bet he goes to Archon because it's not a dedicated anime con, so there's less change of gathering a crowd of obsessed fans

If I were K.C., that'd be MY reasoning hehehe
