So you've got a brothernator on your hands. He can't be bought, bargained, or reasoned with, and he absolutely will not stop until he's gotten you evicted from the family home. Usually they're the moral type, acting to protect their family. You've failed at every attempt to kick him from the nest, and worst of all, your grace period is coming to an end. Your adopted parents are starting to see behind the mask, slowly coming around to the idea that their son's 'crazy talk' about your sociopathic tendencies may not be so crazy after all.

Your last hope is to establish dominance. Gift your new parents a weeklong vacation out of town, arranged as a "thank you for adopting me!". This will buy you a week alone with the meddlesome brat to bring him to heel.

This is a last resort, so use everything at your disposal to break him, to make him see that you're the top dog. This is simply the new state of affairs, the way the world works, and he can either accept it or suffer the consequences. Intimidation works, but is risky. Do recall that much of your physical strength will have been lost in the conversion surgery and, if at any point he senses weakness and calls your bluff on the hollowness of your threats, things will very quickly turn on you. You may find yourself at his mercy, in which case you are best to leave and start again from scratch with new victims.
