Is "Heroes" finally starting to get good? Maybe so. And with it comes the return of Mohinder Suresh, played by Sendhil Ramamurthy.

Of course, that brings up questions about Suresh's father and his research into the people who have abilities.

Some video footage from the 1960s with Dr. Chandra Suresh have surfaced recently, and were released. They were based on his work with a pregnant woman who created tremors. At the same time, the cameraman got some upclose looks at the equations and notes on Suresh's blackboard.

Get all the details in the videos below.

"Heroes" airs Mondays at 8 p.m. ET on NBC.
