It's been approximately 2 weeks since the mission and things weren't the same. Since Jasmine has been staying with Tommy and becoming an official member of his empire, the one thing that she taught to never do is betray Tommy.
Betraying Tommy is like writing your own death wish, and that's exactly what Shawn did when he went behind Tommy's back and plotted with his brother. Tommy knew everything that was going on, he had eyes everywhere, and the fact that one of his trusted members went behind his back and sided with his brother, the person who disrespected their dead father and betrayed him, made Tommy feel deeply hurt and angry.
He didn't regret putting Shawn down, but Shawn's actions took a toll on the group, especially Jasmine, who was violently accused of Shawn's intentions of siding with Tommy's brother.
