After Young Sheldon, producer Steve Holland is looking to bring Sheldon in Georgie & Mandys First Marriage. The boy genius officially wrapped up his childhood in Texas in the emotional Young Sheldon finale. Despite spending years diversifying its storytelling, The Big Bang Theory prequel wrapped things up by properly transitioning Sheldon to his new life in California, as he began his post-grad studies at Caltech. Back at home, however, life will continue for the Coopers. Granted that it wont be the same as Young Sheldon, the offshoot will essentially move on via Georgie & Mandys First Marriage.
