Hassan's mom left him and her husband. When she came back Hassan didn't know who he was, and she told him and he ran off. He was really shocked about her coming back. She takes care of Hassan's child. She's trying to replace what she had done years before that. She wants to fix everything now after she came back. She doesn't want Hassan to feel unimportant in any way. I don't know why he left or what happened after she did but I know she wants her family back and make things better with Hasan.
