Collective memory of Ra's Al Ghuls
There is a belief that Lazarus Pit causes Pit Madness that may last a few days or the longest time, depending on a person submerged in it, as well as that the waters heal the wounded, resurrect the dead and even grant immortality, but it also keeps and shares memories of the people who once entered it. Some get to have these foreign memories after the Pit Madness period passes, and some do not. (It is safe to say most do not.)
Anyway, Ra's has been around for centuries holding onto all his knowledge and experiences he gathered through his life and does not intend to die, but what not many know is that, just like Thanagarians remember their past lives, he shares memories with all his versions across the multiverse.
Usually, it doesn't play any role in anything other than give him some advantage in situations concerning certain people.
His own memories, not the ones that come from his variants, are easier to access and are closer to him, so he doesn't get shaky with his facts.
No one even suspects that his mind is actually a very well organized infinite maze of a library.
But sometimes it all makes Ra's dread some meetings severely, and it is hard for him to explain himself without giving anything out when asked (as he doesn't always manage to hide his displeasure).
It is neither fun nor easy to be the Demon's Head...
(It is just a headcanon/part of my AU. Or is it...?)
