Quantum Leap answered some major questions - but also introduced a lot of new ones - in its shocking series finale. The NBC series, which premiered in 2022 and recently dropped on Netflix, was a revival of the '90s science-fiction series set 30 years after the original show concluded. Quantum Leap followed Ben Song (Raymond Lee) after he made a secret leap through time and got lost in the past. With help from his now-ex Addison (Caitlin Bassett) and the rest of the Quantum Leap team, Ben tried to figure out what caused him to alter history.
