Bruce asks Selina for one more dance.
“Basically, what I’m trying to say is Alfred is Batman.”
The “titles” of Batman Begins showed the symbol of a bat formed in a swarm of bats, the titles of The Dark Knightshowed it in fire, now The Dark Knight Rises shows it in ice. The bats in Begins were a symbol of fear, the titles a metaphor for an identity forming out of shadows. The fire of The Dark Knight was like a wall of fire for that bat, that symbol, pushing through the chaos inflicted by the Joker. Now, the bat is, literally, the cracks in the ice formed by the isolation of Gotham City at the hands of Bane.
