Graduation Match: Part 1 - S1-E51
Stupidity: Zane activates the spell card Polymerization and explains that "by sending some select monsters from my hand to the grave, I can summon a Fusion monster", to which Jaden replies "To the grave?" as if he is completely surprised by the fact that the monsters will go to the grave. Jaden is completely familiar with Polymerization and has used it in nearly every duel, so he should be aware that the monsters will be sent to the graveyard when Polymerization is used. (00:07:42)
