Quantum Leap Season 2 2024

The highly anticipated second half of Quantum Leap Season 2 is expected to be filled with more drama and time-travel shenanigans. 

Five episodes are still set to premiere for Quantum Leap's return in 2024, and the stakes are higher than ever. 

The first half of the show's sophomore run ended with Ben Song (Raymond Lee) contemplating a major decision that could change his life and the Quantum Leap project forever.

Quantum Leap Season 2B premiered on NBC on January 30.

Raymond Lee - Ben Song

Leading the new group of scientists in the revived Quantum Leap project is Raymond Lee's Dr. Ben Song. One of Song's main goals is discovering what happened to Dr. Sam Beckett after his mysterious disappearance. 

Armed with a brilliant mind and a desire to do what's right, Song is an ideal candidate to correct the mistakes of the past. However, things go awry when the lead physicist suffers the same fate as Beckett as he gets stuck in the past while leaping into the bodies of different people.

Ben has had his fair share of ups and downs in Season 2. After learning that the team behind the Quantum Leap has been disbanded, Ben is also heartbroken that his fiance, Addison, has already moved on from him. 

Still, Ben finds a new romantic interest, Eliza Taylor's Hannah Carson, who is a math and physics genius. 

Season 2's first half ends with Ben promising Hannah that he will find her again (whenever that may be), and Tom reveals to Addison that he may have a way to bring Ben back home to the present day. 

Lee is best known for his roles in Top Gun: Maverick, Here and Now, and Made for Love.

Caitlin Bassett - Addison Augustine

Caitlin Bassett's Addison Augustine is a hologram only her fiancé, Ben, can see and hear. 

Within the three years of Ben's absence, Addison has found a new boyfriend in Peter Gadiot's Tom Westfall. With an unfortunate love triangle formed and the three forced to work together, this new dynamic truly tested whether Addison and Ben would ever be able to pursue a relationship.

Season 2 highlighted how conflicted Addison was on whether to keep her current relationship with Tom or pursue Ben knowing that he is still alive. 

Addison even became Ben's hologram during certain missions, complicating things for the pair. 

She eventually managed to move on after talking with Magic about living in the now and not waiting for the future to arrive.

Quantum Leap is Bassett's first major acting stint.

Mason Alexander Park - Ian Wright

In Season 2, Ian delivers the tragic news to Ben about his three-year absence, revealing that he snuck into the then-defunct Quantum Leap program to keep searching for him. 

Ian has also reconnected with former partner Rachel, whom viewers previously met in Season 1.
