Tú y yo, Marston. Eh, peleamos ahora, eh? We fight now!
Translated: You and I, Marston. Hey, we fight now, eh? We fight now!
Note: After Marston kills Müller in a duel, Sanchez takes a nearby woman hostage, and threatens to kill her with a knife. Despite him using the woman as a shield, Marston is able to shoot him in the head.
