The executive producer of "The Big Bang Theory" Steve Molaro confirmed that Sheldon did not board the train and will stay and will continue his relationship with Amy.

According to the show runner, the two will be taking baby steps in their relationship. "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 not. 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," he told TV Line.

It seemed that Sheldon sand Amy will be moving together. There will be minute progress in their relationship, which suits Sheldon's careful and meticulous attitude.

Steve Molaro also hinted that there will be another wedding proposal to happen on season 8 after Penny and Leonard became engaged last season. In season 7, fans saw a huge progress in the relationship of Leonard and Penny. Wedding plans are being talked about by the bosses during the series' hiatus. Also, this could mean that we may hear the wedding bells for Amy and Sheldon.

Aside from Leonard and Penny's good relationship, "The Big Bang Theory" fans are curious whether Sheldon and Amy will follow suit in being engaged after the couple kissed. On the final episode of the previous season, Sheldon had cold feet when Amy asked him to live together. Sheldon was seen boarding a train that made fans speculate whether that was Sheldon's untimely exit. It is still unclear whether Sheldon actually get on the train, which makes the final episode of the previous season a cliffhanger.

"The Big Bang Theory" season 8 premiere date is on Sept. 22 and will include a time jump, which is two months after where the previous season left off.
