Xana decided to get rid of everyone by using the power of Gravity, and Yumi, Odd, and Jeremy went to the factory, but Ulrich had a soccer game, and his Dad was there, and as Odd said: If you're not first, then you're not good in his book. Ulrich had to save Mrs. Hertz though, because she was in the science lab. So Yumi and Odd went to Lyoko, but a huge swarm of monsters reached them, and Yumi and Odd had to clear a path for Aelita, and Yumi created a rock shield with her Telekenesis, but Yumi's Telekenisis didn't last very long, so Aelita decided to go across another way. She ended up getting hit and she fell off the bridge she was materializing. Odd and Yumi were in disbelief. But, Aelita appeared right behind them. Ulrich slammed through the science lab window, trying to save his dad, leaving Sissy with Mrs. Hertz.
