While Leonard (Johnny Galecki) and Penny (Kaley Cuoco-Sweeting) are set to get married on CBS's The Big Bang Theory, fans should not expect Sheldon (Jim Parsons) and Amy (Mayim Bialik) to get anywhere close to that level of commitment.

The Big Bang Theory showrunner Steve Molaro spoke with TVLine in a new spoilers report that revealed Sheldon and Amy will continue to progress at a slower rate through Season 8.

"We're always moving them forward in baby steps," Molaro said, revealed that there is no "set plan in place" for them to take their relationship any further.

"They're on the same trajectory that they've been on since they met, and that is she is continuing to drag him along into this relationship, whether he wants to admit that he likes it or or not," Molaro said. "He's come a long way. She's got him to a place where they hold hands and they kiss and they go on regular dates. While it may not seem like a lot, it's a colossal amount for him."

Sheldon had a bit of a breakdown in the Season 7 finale after if was revealed to him that Leonard would probably be moving out of the apartment. This caused him to go to the train station to possibly leave town.

As revealed recently, it seems that Sheldon will indeed leave town and end up in Arizona in the Season 8 premiere. Leonard and Amy will be forced to rescue him and take him back.

The Big Bang Theory returns for Season 8 on Monday, Sept. 22 at 8 p.m. ET/PT on CBS.
