It's been nearly a decade since Quantum Leap went off the air, but fans of the show are still itching to vault into the body of its creator, Donald P. Bellisario, to figure out what really happened during that head-scratching final episode.

When viewers last saw Scott Bakula's alter ego Sam Beckett, he was trapped in a small-town tavern in 1953 where an enigmatic bartender appeared to solve the mystery surrounding the time traveler's existence. While Bellisario has attempted to decode the ending to Leap loyalists before, he clarifies to TV Guide Online that the bartender was "God, or fate," as he wanted Sam to at last meet the one who had "created him." And the significance of the bar itself? It was a recreation of the pub once owned by Bellisario's late father.

What audiences did understand was the screen epitaph that ended that fateful program's five-year run: "Dr. Sam Beckett never returned home." "I'd say about half the fan base was extremely disappointed that Sam did not return home," Bellisario admits of the last installment, which is airing Wednesday at 4 pm/ET on the Sci Fi Channel. "[But] I used to say, 'To do what? To plant a garden? He's still leaping around out there, still putting right what once went wrong."

If Sam is still hopping about, maybe he's heard the buzz about a possible big screen Quantum Leap reunion. "In the back of my mind I had always hoped that I could get that one going again somehow," says the prolific writer-producer (Magnum P.I., JAG). "[But] Universal, who truly owns the rights to it, has never shown an interest."

In the meantime, Bellisario is feverishly working on his new Supreme Court drama First Monday, which premieres Jan. 15 on CBS. "What we've concentrated on is some basic truths that go on in the Court," he says. "I really wanted to pull the ol' curtain aside like Toto did and show the wizard behind it. Or in this case, the nine wizards."
