wait.....WHAT??!?

Greek Mythology is honestly the most confusing thing in the world, more confusing than math

WOW that's saying something

Greek Mythology family physics is different

so no, Chiron is not Perseus' uncle. When a demigod dates another demigod it's fine, even though their parents are related. for example, an Ares kid can date an Aphrodite kid. If an Ares kid dates another Ares kid......that's weird.
