Nobody seemed to realize it at the time, but evidently this was an early sign of Iceman undergoing a secondary mutation of his own. When he repeatedly tried to evade his regular medical check-ups, school nurse Annie Ghazikhanian recognized that something odd was going on with him and pressured him to show her the wound. Bobby made her promise not to tell anyone and showed her that parts of his chest are now made of ice and he is unable to change them back to flesh and blood. Iceman wonders if he will entirely turn into ice on a permanent basis.
