I am seeing a Young Sheldon episode with Veronica now, who Georgie once fell hard for. The Georgie & Mandy producers should bring back Veronica for an arc at the end of season 3. She could reverse her former position and be the one who pursues Georgie now. Or have this arc at the end of season 4 going into season 5 if they want to delay the inevitable. Mandy would be his first divorce, Georgie marries Veronica and she later becomes his second divorce, then he could reunite with Mandy. There could be a time jump for when this show becomes Georgie & Mandy's Second Marriage.
