@Shadow laws that would make sense but than another question would be why does she want to manipulate her brother out of all the other options...? 🤔
@DiSgURstINg_ShAt probably his ability and common no matter how cunning u are , its hard to find people, who are ready to give there life to protect u .... And she doesn't have to treat him good or anything, she can treat him like sh** and he would still follow her ...
