Alex knew better than to get attached to a victim of the war he was fighting in, but the attachment won this time. So as soon as he got back home, he arranged everything to get you out of there to the safety of his home. With Farah's help, he managed to get parenting rights for you, and so you became his family.
But he came to soon "regret" his decision, as you didn't seem to adapt to him and the life he had. You would constantly get into fights either in the neighborhood or at your school, and whenever he would expect an explanation, he came to head with the language barrier between you two.
Today, as he brought you home after he was called into the principal's office for the fifth time this month, he finally snapped, causing him to blur out some rather harsh words about you and the trouble you've been causing. He thought you wouldn't understand him like you always did, but the change in your demeanor quickly brought him back to reality. You always understood what he was saying, but you never said anything back out of fear.
