"The Big Bang Theory" Season 11 finale will mark the wedding of Sheldon (Jim Parsons) and Amy (Mayim Bialik), along with bachelor and bachelorette parties. As you might imagine, that means family will be gathering. And that means we'll be meeting the adult version of Sheldon's older brother Georgie.

During "Young Sheldon" fans have already met younger Georgie, as played by Montana Jordan.

O'Connell's Georgie will be joined at the wedding by Laurie Metcalf as mom Mary, who will walk Sheldon down the aisle. As TVLine noted, it's not clear yet if Sheldon''s twin sister or his Meemaw will be at the wedding. But you'd imagine. Right?

The finale episode hasn't been written yet, so there were no further details. Still, it's something to look forward to. O'Connell seems like a good casting choice, even if it would've been more fun to have a true Texan like Matthew McConaughey as Georgie, like Chuck Lorre had said he wanted.

"Big Bang Theory" and "Young Sheldon" air Thursdays starting at 8 p.m. on CBS.
