What's on tap for Amy and Sheldon this season on The Big Bang Theory? In two words: orgasms and jealousy.

“We have an episode coming up called the “Helium Parasite Hypothesis,” it will be on in a couple of weeks,” Bialik told EW this week. “Amy starts to feel sexually aroused by someone. She doesn’t know what those feelings are. And Sheldon, we’re not sure if he is feeling jealousy, because he doesn’t know what those feelings are.”

Does this mean things are about to get a lot more serious between this pair?

"I think things are going to get more concentrated,” Bialik says. “They’re going to explore different aspects of the relationship. I can pretty much guarantee you’re going to see Sheldon in the same way you have always seen him. My character probably is going to stay the same. It’s more like, what does this relationship look like with these polarities?"

Hey, as long as it results in hilarious The Big Bang Theory quotes, we're on board.
