What interaction does Nadira have with Tareq in Section 4: Chapter 5? How does she describe this character?

Aisha calls Tareq a lowlife because he dropped out of school and is shady. Tareq summons Nadira over, telling her he hear Abba is in trouble but he can help as there are places to buy what the Hossains need because not everyone gets a green card by playing by the rules. He gives her his cell number before Ali-Uncle calls to Nadira.
