There is no denying that the upcoming episode where "The Big Bang Theory" favorites Sheldon Cooper (Jim Parsons) and Amy Farrah Fowler (Mayim Bialik) finally take their relationship to the next level by becoming more intimate is truly special, and the stars took great care in making it so.

Bialik said during an interview with The Hollywood Reporter that everybody paid particular attention in how the love scene will unfold in line with Sheldon's typical behavior.

"We have a scene where Sheldon and Amy discuss it before we even get to the bedroom, and it's one of my favorite scenes that Jim and I have done together," shared Bialik. "It's very tender and special. As much as Amy really wanted this, it's terrifying for her to have this in front of you, even with the right person and someone you're in love with."

"Especially as adults and those of us who have lived a life of serial monogamy, you forget what that feels like, but it can feel like that - even if it's not your first time," she added. "That's what the writers capture. We had to be careful and walk the fine line between nervous and excited because you don't want it to feel like, 'Ew, maybe she's not ready; maybe he's not ready.' It's so much in the words, but there are a lot of subtleties. You can't be too freaked out about it because then you're watching uncomfortableness, and that can feel like a violation of these characters you love."

Parsons agreed, because he felt that his character is very comfortable with their decision. Even though Sheldon grew up unfamiliar with intimacy, Parsons said that his character feels quite at ease with Amy. And because he loves her, Sheldon feels he can pursue anything with Amy.

"And on the other side of it, because of Sheldon's somewhat odd relationships, he ends up feeling a little less anxious about it than she does because it hasn't been built up in that way for him. This is not something he's been waiting and waiting for. As he says to Professor Proton, 'I understand the mechanics,'" said Parsons.

Meanwhile, Sheldon's mysterious engagement ring might be kept in the dark from Amy for quite some time still.

"That's something we're trying to figure out. I don't have any answers for you at the moment, but the ring will rise again," said showrunner Steve Molaro.
