My older brother wanted to be an Omega. He never did it for whatever reason but when I became a Nupe, or when I was "becoming" a Nupe, he made his feelings on my frat clear. He hates us. LOL! I think one of my frat stole a girlfriend of his or whatever, but he won't confirm that.
My little brother on the other hand has already said that Kappa is the only way he would go.
