X.A.N.A.'s lat attack chapter 4: A new ally?

"Yumi calm down" said the nurse. "You must have had a bad dream induced by whatever accident you encountered. That reminds me your friends never told me how you got so injured. What happened?" "Well..." said Yumi, trying to come up with a lie. "I was riding my bike and ... fell on a rocky area" The nurse didn't seem to buy it for a second then she said slowly "Okay..." Yumi breathed a sigh of relief that the nurse had believed her. "You may leave whenever you feel up to it. Just don't take the bandages off and be careful with your broken leg. We gave you a walking cast so you can still move around." Yumi climbed out of her bed and left the infirmary. As she walked down the hall she took out her cell phone and dialed for Jeremy.
Jeremy picked up and Yumi immediately began talking "Jeremy what happened?" "Yumi? You evacuate the school NOW!" yelled Jeremy. "What's happening?" asked Yumi. "X.A.N.A. is hacking into power supplies to manipulate gravity. You have to get out of there and help us as soon as possible." said Jeremy. Before Yumi could begin to speak again she felt the ground shake with tremendous force and heard a loud explosion. She shrieked as she was thrown off her feet by the force of the blast. "YUMI!? Are you okay?!" yelled Jeremy. Yumi picked up her phone and answered "Yeah... Yeah I think I'm okay. What was that?" "X.A.N.A. fired another laser shot from the satellite. He's targeting you because he can't get us while we are in the factory. Get out of there fast!" said Jeremy quickly. "Right" said Yumi.
Yumi hung up her phone then dashed for the stairs because of the pain in her leg. "I can't run..." she said to herself. She then stood back up and began walking as fast as her legs could carry her. As she rounded the corner she ran into one of her classmates Scorch. Scorch was a tall boy, built more for speed then strength. He had organish-blondish short spiky hair and a scar under his right eye. "Oh hey Yumi." Scorch said. "What happened to you?" "Never mind that now." Yumi said quickly. "You and the rest of the school are in great danger!" "What?" asked Scorch. "Never mind. Can you just help me so I can walk faster? I need to help Ulrich and Od before it's too late." "Okay I'll help you." said Scorch. Leaning on Scorch, Yumi could walk much faster so she started towards the tunnel as fast as her legs could carry her. As the two headed for the tunnel, she filled Scorch in on everything that had happened since they had first entered Lyoko.
