Jack seems to be a kindler, gentler version of his former self...he let the CTU director disprespect him without consequences, and he let that cop that was beating on him off far too easy as well.
Meanwhile Renee is the one showing the cool and merciless brutality that Jack is famous for.
Jack needs to start picking it up next week; I can hardly believe we're 4 hours in and he's only killed 3 people.
