I don't think you ca' really take into account their ages or their relationships because Greek mythology is messed up, most of the gods weren't born as babies while they could grow, they weren't as defenseless when they were born. Also there's so much incest, it's almost normal. You just have to accept it, if you question it, you'll just end up with nothing but a headache.
Would this consider child grooming if they do end up together? He's not caring her for sexual intentions but he cared her because for Metis and also pities Athena so this is actually confusing. Posiedon and Athena aren't pedo x minor or is? (Don't say it's mythology please)
