Yup, Yugi destroyed the evil in Kaiba's hearth, and got him into a coma! Fucking wow. Also we get to see his circumstances explained to us by Mokuba, Honda was saved by him too.
Turns out Kaiba's adoptive father was a real monster, and shaped Kaiba into his own image. How ironic that he ended up loosing everything and his company to his heir and creation. He also freaking killed himself to show what loosing means to Kaiba in this world, as his final lesson. No wonder Kaiba ended up so fucked up.
Anyway the end of the arc, and it was awesome! So much better than how they just compressed it into one episode, that made everyone look retarded and make no sense in the anime.
