Good episode tonight.
It looks like the Kara Stanton/Mark Snow story arc is finished for good. (Other than maybe in flashback sequences).
More generally, it appears many of the major ongoing story arcs from season 1 are either finished or at a point where things are wrapped up for now. (ie. "Man in the suit" investigation, Kara Stanton + Mark Snow, HR being weakened, Elias behind bars). Almost like wiping the slate clean, like a partial reboot.
