The entire staff of the Daily Planet who have seen him without the glasses for several seasons and Perry, Cat etc Everyone at the wedding who saw Clark Kent walk down the isle without glasses or the bumbling persona. This was the same day Superman was revealed to the world. The problem with Smallville is they introduced the bumbling persoa and glasses way too late in the game for them to make sense. Enough people had already seen the real Clark Kent before. I feel like the only way to enjoy CW's Smallville is with selective amnesia.
