I'm going to protect my cousin from a potential predator
Is your cousin in some kind of danger?
He's underage and she's in her thirties. It's fucked up.
Predating on young people is always wrong. Your cousin is lucky to have you looking out for him.
Yea I need to go protect him. Maybe I should have sex with the girl too and befriend her.
No that's not what I'm saying at all. I'm saying you should continue to protect your cousin at all costs.
