Yugi is going to go to the Library and see if he can find any more information on where the Sundering Circle might be. He'll also go looking around the school grounds and, probably to the dismay of everybody, be going underground. He knows there are secret passageways thanks to the Experiment, so it's probably hidden! Aaand finally he'll try to pick Professor King's brain about circles and rituals and see if she's ever heard of anything like that.
