What important news does Tariq bring to Laila, and how do they respond to it?

Soon after Giti's death, Tariq tells Laila that is leaving Kabul for Pakistan. He tells her that he is leaving the next day. Laila is extremely distraught. After Laila becomes upset, she and Tariq have sex. Tariq asks Laila to come with him to Pakistan and marry him. Laila wants to leave, but she realizes her father's life would be over if she left the family. Tariq expects this response, and Laila forces Tariq to leave without an extended goodbye. Tariq yells from outside the front door that he will come back for Laila.
