While Xavier is worrying about Illyana (perhaps something he should have been doing more of recently), S'ym - Belasco's head minion - turns up, takes down Xavier, and lays in wait for Illyana. Oh dear. She uses her mutant power to bring the New Mutants into the mansion (and in a curious bit of timey-wimey, intersecting with a bit of Magik #3), where they start the requisite punching. Teamwork, as usual, proves key. Magma gets to use her powers in controlled combat for the first time, by making a mini-volcano inside, busting up the floorboards. I can see a small problem with that.
Magik recovers. Her spells prove ineffective, so she is forced to resort to the soulsword. With this she threatens S'ym into her service. Stevie Hunter witnessed all of this, so Magik rips a trick from Xavier's playbook and mindwipes her. All that is remembered is Magik's mutant power: the light circles. She keeps the magic to herself.
