Just in case you were wondering, the young Big Three are all grown up. On Thursday, This Is Us posted an adorable behind-the-scenes photo of the 10-year-old Kevin, Randall, and Kate (who are actually 11 in real life) with the 17-year-old Kevin, Randall, and Kate, and it's making us do a double take. Not only do they look SO much older, but they're practically as tall as their older counterparts! In fact, Mackenzie Hancsicsak actually is taller than Hannah Zeile. Where did the time go?
As the young actors continue to grow up, we can't help but wonder what this means for the future of the show. While the young Big Three could continue to portray Kevin, Randall, and Kate at 11, 12, or even 13, they also need to keep continuity. That could explain why the show has already shot the final scene of the series. Maybe there will be a flashback to the young Big Three and they need to shoot it now before they get any older.
Whatever the case may be, we'll just be over here trying to process our feelings over this photo.
