Escobar is seen getting the news that Poison and the other sicarios were killed and puts a bounty on the head of the DEA agent (Murphy). The problem with the scene is that it takes place at what appears to be Escobar's Hacienda Napoles much earlier in the time line of events- however, later in the series it is clear that Poison and the others were not killed at the nightclub until after Escobar surrendered and was living at La Catedral. He had fled Hacienda Napoles long before Poison was killed. He would have been at La Catedral when he received that news. They messed up the chronology of the scene.
