Clear this up for me; does Yusei have amnesia of his past, his name, the duel, what exactly?
Anyway, in the logical land of raw anime, Yusei lost and almost died playing against Kiryu. Large shards of metal lodged in his torso, blood! Yusei Stark, anyone? Fortunately, he recovered, which was cool. Earthbound Gods are broken, yet kind of wierd since their effects require there be no Field Spell, even though Speed World is...guess it doesn't count.
Then, Rua, Ruka, Hanagi, and spikey-hair-guy went to go save Aki. They got trapped, and Rua was forced to duel, which finally let us see some Psychics in the anime, including the ever-amazing Thougt Ruler. That card is too good. It's heavily foreshadowed that Power Tool Dragon is in fact some version of the fifth dragon, since it actually looks at Rua with some feeling after he's struck down. I was really hoping for Godwin.
