He will only be able to read what the others are thinking at the time.. so if you are interacting with him, the owner of the character could put stuff like what they are thinking.

But he has only shown symptoms and can barely use his powers, and I changed them around a bit.

Karl will be taught to use his powers for good anyways, so he wont go erasing someones memory, or reading there thoughts without permission.

He doesnt have telepathy anymore. :3
