About the Professor[]

When Sam leaps into FBI Agent Peter Langly who's trying to Dana Barrenger, a woman who testified against a one Nick Kochifos, a dangerous criminal she used to work for, he chooses to hide out in the cabin of his mentor from MIT Professor LoNigro, it is revealed during the episode that he and Sam first formulated the string hypothesis that underpins the Project Quantum Leap together, in that very cabin.

After Sam completes his duties he fails to leap, it is only when Professor LoNigro enters the cabin to find Peter and Dana, that Sam gets an opportunity to tell him, as he doesn't know who Sam is, that the string theory "works".

Earlier in the episode Sam mentioned the last time he visited the cabin was some months from the time period in which the episode is taking place. This leaves the possibility that Sebastian had invited Sam to his cabin to formulate the theory because the future Sam had already informed him of its success; effectively making the force that's driving Sam responsible for quantum leap's creation. Perhaps LoNigro got the message through Sam, as Peter.
