Sartorius predicted that Jaden and Aster have joined forces, but there is another that can't be swayed and could ruin Sartorius' plans. He traveled to Duel Academy to meet this threat, Hassleberry. Hassleberry and Sartorius dueled each other, even though most of the others, but Jaden, believed Hassleberry could win. Sartorius dueled the same way he did Chazz, with cards whose abilities are determined by Hassleberry's decisions. Sartorius won, but Hassleberry wasn't affected by his power to turn into a Society member. It was revealed that Hassleberry broke his leg when he was a kid, but was saved when the bone was replaced with a dinosaur's bone. The next day, Crowler announced the arrival of a new student, Sartorius.
