For today's clue, I'll confirm that commenter Catti is indeed correct in the identification of contestant #24 as the person of interest.
But unless I'm missing some extremely subtle allusion, Catti's "for the win!" isn't actually an identification of the person. So, barring Catti returning to prove me wrong by explaining what I'm missing, I'm considering the quiz still in progress.
There'll be one more clue in a day or two if necessary.
Have at it.
