'The Big Bang Theory' boss Steve Molaro talks Sheldon and Amy's kiss and previews what's next for Shamy

The Big Bang Theory's Sheldon (The Big Bang Theory) and Amy (Mayim Bialik) have one of the most...interesting...relationships on television. Amy's constant frustrations are understandable given Sheldon's agonizingly slow progress, his general obliviousness and his social awkwardness. But the two took a big step forward on the show's Valentine's Day episode when they shared a real kiss!

Showrunner Steve Molaro spoke to EW.com and revealed some of the backstage developments that led to the crucial moment.

"We knew we were going to do this Valentine's Day episode where Amy manages to get Sheldon to go up to Napa for the weekend by using the train as bait. And you know, their relationship is great, but I think there's only so much Amy can take. We do need to keep it moving forward even if it's in baby steps, and I was just feeling that it was time. She deserved a big win, and this seemed like a good way to get to it. Rather than it coming from his excitement, [we wanted] it to almost stem from an argument. It seemed like an exciting way for it to happen."

He also previewed what comes next for the couple that fans affectionately call "Shamy."

"That's an important question. We're not going to do too much relationship stuff between Sheldon and Amy right away, but obviously this is a moment that occurred and you'll hear about it here and there. But sometimes we like to make a big move and then put that aspect down for a few episodes before we revisit it. But it happened. He clearly didn't dislike it. It turned out to be not as bad as he thought it would be - as he described to Leonard when he got home. And we'll see where they go from there. I imagine she would want more than that or she'll try to work that into the way hand-holding has sort of become a regular thing. Maybe date nights will end with some sort of kiss. I don't know. To be determined."
