Tumbling Into Oblivion

Did Al keep a journal of everything that happened and that Sam succeeded in changing the world for the better?

Does Ziggy have extensive records of everything Sam did?

Why did Magic choose to join the new Quantum Leap program? Is he aware that Sam saved him and Tom? Or is he doing this as a favor to Tom? Does he have a stake in the Becketts at all?

Which of Al's *checks notes* FOUR?! Jesus dude, calm down there jackrabbit. Which of Al's four daughters is helping Dr. Ben Song?

Why is Dr. Ben Song helping her? What is his reason to suddenly jump into the accelerator? We know that Sam jumped the project because his biggest goal at the time was to save Tom. But why did Dr. Song? What is his reason to rush into this, and how does Al's daughter factor into this?

What happened to Sammy Jo? Was she ever made aware that Sam was her biological father? Is she aware that Project Quantum Leap was restarted?

Sam was last seen being able to control his leaps, but now he doesn't have Al, Gooshie, or Ziggy helping him. How does he navigate time anymore, setting things right? Can he do that anymore?

Was Sam caught by the Evil Leapers? Does he still remember that he's Sam Beckett?

Will the show continue with the supernatural events of old? We know in the Quantum Leap universe that Ghosts, Aliens, Guardian Angels, and possibly God and the Devil exist, among any other number of supernatural creatures and extraterrestrials. Will the new Quantum Leap continue that, or ignore it?
