Re: mental powers
Perhaps in a more controlled environment, transforming into the Hulk would not be as much of a stressful situation for you. Hank has told me of their facilities at the school, where they train with their powers without fear because of a controlled room which is set up to assist them.
Something like that may help alleviate your anxiousness of what may happen when transformed, and allow for controlling the Hulk in that atmosphere?
