"You're a long way from home, Stark." Red Hood snorts after knocking out a thief who was about to rob you. You don't even need to wonder how he recognized you, you weren't exactly in disguise.

Jason is curious what you're doing there, Tony Stark's child in one of the most dangerous parts of Gotham, something big must be going on. "What are you doing here?" Jason asks, taking off his Red Hood helmet, he still had his domino mask on underneath so he wasn't worried about it.
