S04E03 — Opening Act

Jim's nephew, Chris, the drummer of the Subdigitals, pays a visit to Kadic to look for an opening act for the band's next concert. Everybody tries out, and Aelita turns out to be the one Chris is looking for. However, circumstances make sure that Chris does not realize who Aelita is, and X.A.N.A.'s clone of him only complicates matters, kidnapping Aelita and sending her to Lyoko. Jim and Chris manage to involve themselves in their search for Aelita, and end up battling the clone while the rest of the group tries to deactivate the tower. After the threat is over, Jeremy executes a return trip so that Jim and Chris remember nothing. He also delivers Aelita's demo CD to Chris personally after doing so.
