It was literally in his blood. Mohinder Suresh spent his life following in his father's footsteps and continued to do so even when the man was dead. A man or science, a man of fact, he still had no trouble believing that Heroes could exist. Or that he, one day, might become one of them.
Mohinder is played pre-injection. He does not have super strength and if his player has her way, he never will. Heroes don't need superpowers to be brilliant.
I am not Mohinder Suresh. Sendhil Ramamurthy just lends a face. This is for fun!
