so apparently it's not illegal to date at any age, but sexual intercourse is different depending on the state. In california as long as the age difference is less than 3 years it's okay, so for Tyson that would leave 17 year olds open and for Skylar anyone above 16. That is until they become legal adults. I'm not sure what is the exact law for other states. Either way who cares, it's Camp Half-Blood and technically everyone in the camp is related somehow so I'm sure laws are being broken there often lol
