Realllly good episode; basically topped the entire 5th and 6th season by a mile! and this is why:
1. They kept going with the "flow". Seems like they kept writing themselves into corners and then writing themselves out. If they kept writing like previous two seasons, Debra would discover his "tools" probably in the finale; but this time the writers went right to it.
2. No "main" "bad guy". That aspect always seemed forced after the success of season 4.
I think this show can redeem itself and make those of us who absolutely hated season 5-6 come back again!
