Tony goes with Omar to meet Sosa, Sosa in turn kills Omar and tells Tony that Omar was a police informant. Tony believes him then negotiates a deal without Frank's approval.share
Tony returns to Miami, and an angry frank points out that Sosa may very well have been most likely lying. It end with Frank telling tony that the people who last in the drug business are the guys who fly low and straight, but the guys who don't last are the ones who want it all, and in gaudy ways. the latter pretty much the opposite of what tony did.
Did Sosa manipulate Tony, was Omar never an informant, and was Tony better off staying true to Frank?
