In the final episodes of The Big Bang Theory, the characters Penny and Leonard's storyline took a surprising turn with Penny announcing her pregnancy. The reactions from the actors portrayed mixed feelings about this development.

Kaley Cuoco, who played Penny, was onboard with the decision for her character to become pregnant. However, Johnny Galecki, who portrayed Leonard, had a different initial reaction when he read the script. He admitted that he didn't quite understand it at first and had conversations with showrunner Steve Molaro about the possibility of Penny and Leonard not having a baby.

Steve Holland, another showrunner on The Big Bang Theory, seemed to share Galecki's sentiment. He expressed that the pregnancy storyline felt abrupt and lacked a proper build-up. Holland acknowledged that it could have been handled differently in the final episodes leading up to the series finale.

Ultimately, the mixed reactions from the actors and showrunners highlight the different perspectives on Penny and Leonard's pregnancy storyline in the final season of The Big Bang Theory. While Cuoco supported the decision, Galecki initially had reservations, and Holland recognized the potential for a smoother narrative transition. Despite these varying opinions, the intention was to emphasize the enduring friendships and love among the characters.
