While The Big Bang Theory looks towards potentially ending its series, Young Sheldon is just getting started and experiencing a lot of success. As a spinoff, Young Sheldon owes a lot of its success to The Big Bang Theory, so it would be cool for fans to see the two have a crossover episode before the flagship series ends. Chuck Lorre previously stated a true crossover between the two shows will likely never happen, however, fans shouldn't be surprised if some characters from Young Sheldon start popping up in Pasadena:
There are young people in Young Sheldon's life that we might someday meet on Big Bang Theory as adults.
With Young Sheldon taking place in the past, it only makes sense that any true crossover between these two shows would happen on The Big Bang Theory. Of course, there's always a possibility that actor Iain Armitage could appear as Sheldon in a dream sequence or something of that nature, but Chuck Lorre's comments to press at the TCA winter press tour (via EW) don't appear to indicate that. It sounds as though Lorre is hinting that someone from Sheldon's childhood who hasn't already been on the series may be making their way to The Big Bang Theory, but who?
When asked who he would like to see from Young Sheldon in The Big Bang Theory, Chuck Lorre specifically mentioned he and the crew all love the character Billy Sparks. Lorre said it would be great if Sheldon's childhood bully were to end up in Pasadena, although he also indicated it wouldn't happen unless the team believed they could get it right.
There's also a strong possibility that Chuck Lorre is hinting Young Sheldon character George Cooper Jr. will soon appear on The Big Bang Theory. Sheldon has referenced his brother many times throughout the series' run, with the latest mention of his brother happening in the midseason premiere. Even though Sheldon went against his mother's wishes and picked Leonard over George for his best man, there's still a strong chance the character could make his debut at Sheldon and Amy's wedding. Lorre did confirm the team talked about bringing George to The Big Bang Theory and even name-dropped Matthew McConaughey as his "dream guy," to play him.
