Routine

For some time now, our heroes have become somewhat weary of fighting X.A.N.A. all the time. Tired of the routine of it all, and of Yumi's seeming indifference towards him, Ulrich starts seeing another girl, which makes Yumi angry, and which causes a fight between our bashful lovebirds... At the same time, a tower is activated on Lyoko, but none of our heroes can work out what X.A.N.A. is up to. Still in doubt, Ulrich, Yumi and Odd are sent to the virtual universe, and they realize that they have fallen into a trap. If they attempt to come back to the real world, they will be annihilated once and for all! This fight "to the finish" completely changes our heroes' perception of their mission: this time around, it's not the usual routine- and it helps Yumi and Ulrich to work out their differences...
