Since we're on the subject, of Yu-gi-oh, I always wondered, by the time the lead cast went to the island (this was the first season), were none of Yugi's friends aware of his alter ego? I remember watching the dub and while I don't remember exactly who Yugi was dueling, they were pretty far in, and Yugi transformed into Dark Yugi multiple times already in front of his friends, and the the girl suddenly notices that Yugi acts differently and is taller some times. I wasn't sure if it was a dumb dub mistake or what.
Also, the manga is infinitely better than what we got in the anime (either dub or the original). When did it turn into a shitty card game?
