About Abigail[]
Sam as Sheriff Clayton Fuller, Abigail's father, in scene with maid Marie Billings (Fran Bennett) and a young Abigail (Kimberly Cullum) in "The Trilogy:Part I".
Sam has to save Abigail not once, but three different times (first into a leap as her father, Clayton Fuller, second as her fiancée, Will Kinman and third as her lawyer, Lawrence "Larry" Stanton III – "Trilogy", parts 1, 2, & 3 respectively). When he leaps into the man she is set to marry, he falls in love with her himself and fathers a daughter, which turns out to be Sammy Jo. Sammy Jo would have high IQ and a photographic memory, just like Sam. Later, Al reveals that Sammy Jo is to become a part of Project Quantum Leap in order to find a way to bring him back. The part of Abigail as an adult is played by actress Melora Hardin in For Your Love: Part II and The Last Door: Part III. The part of Abigail as a child is played by actress Kimberly Cullum (who also plays daughter Sammy Jo in Part III) in Trilogy: Part I.
