[last lines]

Bruce Wayne: [presenting a "Gray Ghost" video to Trent] Could you make it out to Bruce?

Simon Trent: [signing the video] Here you go, Bruce!

[Wayne starts to leaves, then turns and looks at Trent]

Bruce Wayne: You know, as a child I used to watch it with my father. The Gray Ghost was my hero.

Simon Trent: Really?

Bruce Wayne: [quietly to Trent, in a familiar tone] ... and he still is.
