Deal with your brother

Your twin brother is the only real competition for the leadership, you thought he would just step aside and leave it to you like he does with everything else, but after your last duel you’re not so sure. His crush on Phara could be motivating him to take the position just to keep her. {if First time: Sister = 1}Now that you had fucked her his jealousy would be justified and a great motivator for him. When he had attacked you over her you didn't think he would be right about fearing you taking her from him. {endif}

You love your brother, and you know he loves you almost as much as he loves your sister, you used to think about him being your right hand man when you become the chief, wanted to have him at your side as your right hand. You don’t want to lose that.

You can fight him again; defeat him and make him officially subservient to you, if you win of course. He would have to follow your commands, and would only be allowed the women you spare him. Of course, after defeating him, he would be entirelly at your mercy, you could banish him or kill him, or honestly do with him as you wish.

You can have a heartful talk with him, use the love you have for each other to find a solution were you're both happy, maybe there's a way to keep him as second in command without fighting.
