From the Batcave: Damian's clones
At the end of Morrison's run Ra's is shown to still have many Damian clones in his secret lair. What happened with these clones? After Damian died Bruce went on a quest to bring back his son. Naturally it lead to a conflict with Ra's that we saw in "Batman and Robin Vol. 6 - The Hunt for Robin" storyline. In Batman and Aquman #29 (or just Batman and Robin #29) we see Ra's trying to use those clones against Batman and Aquman. They obviously fail and Aquaman takes them under his own protection to Atlantis due to whole "nurtured by whales" thing. Eventually Damian came back and one of the things he did was visit Aquaman in Batman and Robin #39 to see how his clones are doing. He says they are his family and with Aquaman's help moves them to some remote island where they can live in peace. Last time we see them is Robin: Son of Batman #5. Damian during his adventures ends up on the same island, there is a battle and his clones end up sacrificing them
