At this point, [Tuco and Pablo] start scrapping like children, while Blondie looks secretly on. 'Please forgive me, brother', says the thoroughly ashamed Padre Ramirez. Tuco walks out, without turning back, then boastfully tells Blondie: 'My brother, he's crazy about me... even a tramp like me. No matter what happens, there'll always be a bowl of soup'. Blondie replies: 'Well, after a meal, there's nothing like a good cigar'. Tuco wipes away his tears and proceeds to eat the cigar, a broad grin returning to his face.
