S1·E22 Routine

Ulrich is getting tired of getting being rebooted so many times and waiting to find out if Yumi has feelings for him or not. He thinks these are his only troubles, but he is not counting on two things: 1) Sissy getting in the way again and 2) Xana's latest attack which is quite deadly. He disconnects the scanners that makes the return to the real world if he or any of the gang lose all their life points. Instead of returning devirtualized, they could die in Lyoko. Can Aelita shut down the tower in time?
