Y'all are forgetting about Konnan. Even though his story has not been revealed yet, his son the driver will only be reprimanded "if" he and Tasha ever does something and Ghost finds out about it. I don't think Ghost will actually kill the son of somebody that close to him.
Other observations:
Seeing Tommy and Tasha smoking together and sharing advice on relationships is confirmation that Tasha probably played a bigger role as the crew came up. Did you see how Tommy reacted when he was told that Ghost was cheating on Tasha? Tommy's relationship to Ghost is exactly like Raynathan to Romello in Sugar Hill. They disagree on a lot of things but for all that they have been through, that is much love and loyalty. With Tasha, it's like he has the utmost respect for her. Other than this new chick he's with, Tommy does not treat other females with the same kind of respect.
Going back to Konnan, the only thing that has been revealed is that he was busted on a weapon's charge. He must have been heavy with muscle because in one of Tommy and Ghost's conversations, they agreed that if Konnan were still around, no one would be hitting them. I figure we'll learn more about Konnan sooner or later...
