Big Bang Theory Boss Weighs In: Did Leonard and Sheldon's Parents Hook Up?

Bazinga or boom chicka wow wow?

We've long known Judd Hirsch would play Leonard's (Johnny Galecki) dad in The Big Bang Theory's Season 9 finale, but what we couldn't have seen coming was that he'd hit it off with Sheldon's (Jim Parsons) mom Mary (Laurie Metcalf). And we definitely didn't foresee the two would end up dashing off into the night in the same cab for a nightcap at the same hotel. Did they hook up? Could they be about to make their sons literal bros in Season 10?

"I think it might be a leap to those people getting married," showrunner Steve Molaro said in an interview with TVGuide.com. "The truth is, we don't know what happened. Nothing is set in stone."

He urged us to stick to the facts: Alfred and Mary discovered they were staying at the same place, decided to have a nightcap and split a cab. What happened after that - or even, concurrently with that - is still being determined. The plan as of now, he said, is to pick up where we left off: the next day, with everyone piecing together what happened the night before. "There are other stories about what happened that night," he teased.

Big Bang boss: "maybe Season 10 is the ending point."

We'll also learn more about Raj (Kunal Nayyar) and Howard's (Simon Helberg) not-unfounded paranoia that the government is watching them. "We certainly have not seen the last of [that story]," Molaro said. As we learn in the finale, the Air Force has taken note of the guidance system the gang of geeks has created and Uncle Sam is very curious about what military applications it might make possible.

Of course, this leaves out any mention of Sheldon's long-awaited proposal to Amy (Mayim Bialik) or Bernadette's (Melissa Rauch) baby bump watch but you know by now those omissions weren't accidental. "I think it's sort of the nature of cliffhangers that they end abruptly, and people are left wanting more," he said. "That's intentional. This is our ninth one in a row."

We're looking forward to the next one.

The Big Bang Theory will return for Season 10 in the fall.
