Is it called rape if a brother has sex with his own sister?

It is incest and illegal. Depending on the ages, it could be statutory rape. And if the sister did not consent it would be rape as well as incest.

Did she have sisters and brothers?

Yes, I know she had a sister because her sister is actually a drummer on the show and on stage. But I'm not sure if she has others.

Thanks for the feedback!
