Sean definitely holds things too close and then erupts when things boil over. I dont see his character changing all that much but I do love the effect Escobar has had on him. Escobar has given him confidence... I mean, Sean has punched out two guys and confronted the man having an affair with his wife. Without Escobar, would have he done it? I think Sean's character will continue to evolve through the end of the season as Sean battles his own inner demons. Its good to see Escobar returning by sending Sean and Christian a ham for Christmas! LOL...
