What happened to waleed and Fatima

Waleed is a robot, not speaking, laughing, or ever expressing emotion. However once they arrive in Berlin, and Ruthie hands him a white corduroy rabbit, Waleed finally breaks into a smile. This shows how recovery is possible, even for a child who has experienced such severe trauma. Fatima much of the novel grieving and desperately searching for her daughter in all of the refugee camps they can find.

Fatima drowned... :)
