When The Big Bang Theory returns on Thursday, Amy and Sheldon will take the next step in their relationship.
As EW first revealed, Sheldon (Jim Parsons) will open up to Amy (Mayim Bialik) about a weird secret he’s never revealed to anyone. “They explicitly talk about that this is a new level of trust, and that’s really special,” Bialik tells EW, hinting as to what the secret is: “It’s along the interest in Sheldon as a spectrum-y person kind of information, and it’s a really sweet episode.”
While the revelation of a secret doesn’t sound as monumental as the duo finally sleeping together earlier this season, it is a big moment for the couple, whose relationship has moved at a relatively glacial pace since season 3. “The [writers] are doing one thing after another to keep that relationship advancing without shoving it into the future,” Parsons says. “This is one of those things that doesn’t necessarily change anything from a viewers’ perspective on a day-to-day basis of watching the show, but in a subconscious way and from the groundwork of the show in general, it adds a layer of something between them.”
