Although not easily visible, there is a distinguishing mark that both remaining League of Shadows leaders bear. The curved scar on Talia al Ghul's back, which Bruce briefly runs his finger over, is also seen the side of Bane's head. The exact significance of the scar and its shape are unknown, but at the very least it gives a concrete and foreshadowing connection between the two terrorist leaders. Like John Blake's jacket stripe, no clear images of the scar are online yet.
