Fans will remember that George Sr passed away in Young Sheldon’s final season after suffering a heart attack – though the death was expected given fans already knew that Sheldon’s father died when he was 14.
Opening up about the decision to air the death when they did, co-showrunner Steve Holland told TVLine: “We thought, ‘Is there a way to do it and still catch people off guard?’

“So the thought of doing it not even in the penultimate, but in the antepenultimate episode, might be a way we can still catch them off guard.
“George’s death was a huge part of Sheldon’s growth as a person. To deal with that death was important to Sheldon as a character, especially as he’s about to go off to Caltech.”
In other news, it was recently confirmed that Young Sheldon’s Will Sasso and Rachel Bay Jones will be reprising their roles as Mandy’s parents Jim and Audrey McAllister in Georgie & Mandy’s First Marriage.
