Japanese Pokemon Scarlet and Violet players have found an Easter egg they believe references Pokemon Sword and Shield's chronology. It may also be a direct nod to the character Sonia, who plays a key role in the earlier Nintendo Switch games. It's rare for Game Freak to acknowledge the chronology of events in the Pokemon franchise, instead preferring an ambiguity that allows for a more malleable timeline. Yet this Pokemon Scarlet and Violet Easter egg is very direct with its implications.
