"X.E.N.A.? Well, keep this to yourself, but one night I went down to the factory, and I saw an error on the screen. It read "X.E.N.A. Activated WARNING!" I thought it was one of Jeremy's projects, so I clicked it out. That's all I know about X.E.N.A. Oh, and one more thing, after I clicked out the box, my character on Lyoko looked slightly different. Maybe it was my imagination. Oh well. That's all I know."
