Peter Bishop grew up as the neglected son of a mad scientist.
After his dad's mental institutionalization, Peter aimed to make himself as different from his father as he could. He's a college drop-out that passed for several months as a chemistry professor, along with an intuitive mathematician with a gambling problem.
Peter is now a civilian consultant for the FBI.

Peter: I've never met anyone who can do the things that you do.
Dunham: Peter, I'm scared.
