They were born of a woman that even they knew nothing about.
A woman who hated everyone and loved no one, and it seemed like her own kids were added to that list. Would anyone ever be able to get through to her? Maybe yes and maybe no, but one thing was sure, this was no kind of brotherhood.
Carl looked into Mustafa's eyes, talking to him in the only way they had known how. The only way that they had taught themselves to. Their secret code involved ten seconds of unbatted eyelashes. If they could both do that, then they were indeed brothers.
