Answer: 1. After losing consciousness a second time, George wakes up in the hospital and is told by Dr. Brunder that instead of the tumor destroying brain function, it has been stimulating it not only making George hallucinate seeing a bright light, but, was also responsible for giving him his abilities.

If George had tried to use telekinesis to remove the tumor, he would probably have ended up killing himself in the process.
