Umm... i've been calculating their ages and the math isn't looking so good

need to see ur calculations bc my brain hurts

The servant said it had been over 10 years since he started archery, and he started at five, so let's say that he has at max, 17 years now. Because how far "over" 10 years can it be? 2 years? 3 years? Still, if he has the same age as his uncle in that time, let's say 17-5, they have a 12 years age gap, so his uncle must be in his late 20s
