We're just not going to mention how his brother raped him? We'll slide past that? Ok
Assaulted or attempted to mark him is the better term. The thing is, this is a fictional world unlike the real world, the little brother was too young, barely a teen, and had no control that's why that incident happened. That's why not many is blaming him, it's an accident that was inevitable and harmed both of them.
Wtf am I reading rn.
