Zack heard Rex telling him where his powers came from and his eyes widened, "Dude, there are ladies present! You can't talk about your nanites out in the open!" He kept his voice low and stepped close to keep Rex's dignity from the women that were present. Rex began flapping about hurting someone and the blonde woman had berated them about disappointing their teachers and Zack's mind went to Angeal back at ShinRa. His mentor had only just begun training with him and he was undoubtedly upset with him for being late. He wondered whether this organisation that Agent J seemed to be a part of had sent a formal message to Angeal or the Director to notify them of Zack's absence. He didn't want this being missed by them and ruining his chances of making first class. He looked at Link, then Rex and frowned, "Rex did you get an invitation? I don't remember seeing one.. unless it was cryptic and I don't think I'm very good at those kinds of messages.." he admitted.
