Breaking Bad, Season 4

Gus:
I can give you the highlights. Your nephews grew impatient. They continued to press me for my permission to kill Walter White. When I wouldn't give it, they settled instead for DEA agent Schrader. But a phone call was placed to Agent Schraeder moments before the attack, thus giving him the upper hand. Marco, shot in the face and died instantly. Leonel lingered for several hours. The warning call to the DEA agent, Juan Bolsa may have some insight into who placed it, for yesterday the federales raided his hacienda, and in the confusion, Juan was shot dead. An accident, perhaps. A mistake made by his own men. But we may never know. At any rate, I thought you should hear it from me. [Gus pats a furious Hector on the leg and stands up to leave] This is what comes of blood for blood, Hector. Sangre por sangre.
