Gustavo: "I told you before. You will not kill Walter White. Not until my business with him is concluded."

Marco Salamanca: "We've waited long enough. We won't wait any longer."

Gustavo: "You'll have to. The decision is not yours to make. Explain to me...why this man White? He betrayed your cousin Tuco, yes. But he's not the one who murdered him. Was there not another man who pulled the trigger?"

Marco Salamanca: "A DEA agent. Bolsa says the DEA is off-limits."

Gustavo: "North of the border is my territory. My say. As a show of respect...I say yes. The agent's name is Hank Schrader. May his death satisfy you."
