“This means that Red and Blue were 11 in RB/RS and 14 in GS/DP as GS/DP events happen 3 years after RB/RS. It's unknown how much time has passed between GS/ DP and BW but Red and Blue are still kids in the world tournament in BW2, so they must be like 14-15 in BW and 16-17 in BW2 as BW2 events happen two years after BW. This all mean that Red and Blue are still teenagers in XY as it's events happen during BW2. So unless there's a huge time span between XY and SM (which would be weird as it never happened before), they should be around 18-22 in SM.”
