Well to kick it off, Grant Morrison's Batman started off with the introduction of Damian Wayne. It's only fitting that it comes to an end with his death. Damian Wayne's Death is a tear jerker because it highlighted all of the character development he underwent under Morrison's pen. By the end of the arc, he was desperately trying to get the approval of both Bruce and Talia, and his decision to no longer kill and look for the best in his mother was what lead to his death.
The death of Knight Cyril Sheldrake. Throughout Morrison's run, he'd been built up as a former sidekick-turned-broken drunk-turned-superhero struggling valiantly to make up for all the time he lost in his alcoholism, but who was constantly overshadowed by his younger, more competent sidekick Squire... and then he goes up against Heretic and is mercilessly slaughtered.
The last issue and the fallout from the entire run. Ra's al-Ghul is freed from his prison and steals back the coffins of Talia and Damian from the Wayne cemetery. Bruce, wanting to retire after losing so much and going through so much, finds that he cannot just hang up the cowl. Batman Inc. is dissolved, accomplishing its goal of stopping Leviathan but losing too much. The Batmen Of Many Nations will go back into obscurity. The Batfamily will further dissolve, reform and repeat as seen in the other Batbooks. Dr. Hurt and the rest of Darkseid's machinations for revenge of Batman are long in the past and are just so much filler in whatever Black Casebook they were written in. The Joker has reinvented himself and will continue to do so as long as he lives. Attempts to investigate Spyral will most likely result in nothing of real note; and Kathy Kane, revealed to be alive, will never meet Bruce again. Damian is dead, and there are no more Lazarus Pits to bring him back; as is his murderer the Heretic, Damian's younger brother/clone. Jim Gordon reflects that every time Batman is knocked down, he will return stronger and better, but Batman's mission may never end, with no peace. And as the League of Assassins reorganizes with the return of its founder, Ra's declares he will have revenge against the Detective for the deaths of his daughter and grandson, he reveals that he still has the clones of Damian and he will use them one day, in the shadows. Batman's journey goes on. So it goes.
