As The Big Bang Theory prepares to expand once more, the franchise faces a familiar dilemma—what to do about Penny. With Stuart Fails to Save the Universe marking the series’ first real sequel, longtime fans are hoping history doesn’t repeat itself.
Kaley Cuoco has never hidden her affection for Penny or her openness to returning. That’s what makes past choices so frustrating. When Young Sheldon wrapped without giving Penny a proper on-screen moment, it felt less like a creative decision and more like a glaring omission.
Now, the rules have changed. Unlike earlier prequels, Stuart Fails to Save the Universe exists firmly in the present-day canon, with a multiverse twist that practically invites familiar faces to drop in. If there was ever a project built to welcome Penny back—even briefly—this is it.
Beyond nostalgia, her return would serve a real purpose. Penny is the emotional bridge between the hyper-intellectual core of the show and the audience. Removing her weakens that balance; bringing her back restores it instantly.
