Kaley Cuoco has nothing but great things to say about her time in The Big Bang Theory, and it's the reason why Penny's return in the new spinoff is entirely possible. Despite its continued popularity, The Big Bang Theory ended in 2019 with an emotional send-off to the Pasadena gang that was largely satisfying.

 Sheldon achieved his biggest goal — to win the Nobel Prize in Physics, with his work in tandem with Amy. Meanwhile, the rest of his friends rally behind them, although they, too, had their respective storylines.

It's no secret that one of, if not the most divisive aspects of The Big Bang Theory finale is Penny's pregnancy reveal, after she insisted that she didn't want to have kids. After stagnating her and Leonard's collective storyline for years, the CBS sitcom scrambled to come up with a conflict for the pair's final narrative.

 Ultimately, the send-off featured a surprise twist that not only was she expecting, she was also happy about it. This wasn't the first time that The Big Bang Theory shortchanged Penny, however — something that people involved in the series retroactively acknowledged.
