- He literally says 'we have been around for 1000 years and since Nolanverse is devoid of any fantastical elements, passing the torch is the only possible explanation.
I always thought he meant the League of Shadows, not a single position.
- Her name is Talia Al Ghul from Doylist perspective but not from Watsonian.
She calls Ra’s Al Ghul her father. It may be an interpretation that Al Ghul is a name, but so is the title interpretation. And imho the name is far less of a stretch.
But that doesn’t mean Henri Ducard became a Ra’s Al Ghul or Ra’s Al Ghul became the League of Shadows. It’s like a religious thing, like christians consider themselves reborn after baptism.
I can see where you’re coming from, I’d expect some quote like “I am Ra’s Al Ghul now” or something.
Again, I can see your interpretation, but I think Ra’s Al Ghul simply being a name is far less a stretch and requires fewer assumptions.
