The Director (No. 24) Conclusion provides examples of:
Bittersweet Ending: While Reddington was able to force Hitchin to free Liz from all the charges planted by the Cabal, the charge of involuntary manslaughter was not allowed to be taken off by the Acting Attorney General, which meant that Liz can't be employed in a law enforcement capacity ever again.
Disc-One Final Boss: Reddington neutralizing and then dumping the Director to his death from a flying jet marks the end of their conflict.
Do with Him as You Will: After the Cabal decides the Director has become too much of a liability, they tell Reddington this, with the strong implication they know Reddington wanted him dead and they approve.
