Iain Armitage, known for his role as young Sheldon Cooper, shared a heartfelt Instagram post bidding farewell to his onscreen dad, George Sr., played by Lance Barber, in "Young Sheldon." The character's departure aligns with the storyline from "The Big Bang Theory" where Sheldon's father dies when he is 14. The final episodes of "Young Sheldon" will air next Thursday on CBS, marking a significant moment in the series.
