Several Young Sheldon cast members crossed over to Georgie and Mandy's First Marriage Thanksgiving episode that aired this week. Lance Barber's character of George Cooper, Sr. was missing since he was killed off near the end of Young Sheldon. But since you see a bunch of dead people on Ghosts, Lance could reprise his role as George on Ghosts as a free range ghost visiting the mansion. The concept of free range ghosts was introduced when Pete discovered he could leave Woodstone Manor. Both Young Sheldon and Georgie/Mandy have led into Ghosts on CBS Thursdays.
