|Appeared on:||Quantum Leap|
|Episodes appeared in:||All|
In The Leap Back Sam used the accelerator again to be replaced with Al and to save his life. He had to sacrifice his freedom but he saved Al.
In A Leap For Lisa, the young Al Calavicci at the Waiting Room was catapulted back into himself, but to a time little earlier than the time Sam had leaped into him. This was done in order to fix a mistake in the past, which was impossible to fix by Sam at the time.
