Moving to match pace with the younger, Luke gives a faint smile. He, most certainly, understands how important this must be. The idea of people getting hurt is...more than enough to have him ready to do what he can to help, too. He blinks a couple of times at the name, "Robin, huh?"

The mention of him being a superhero has him lifting his brows. He's heard about some of the superheros, here. Well, if this Robin is still around, Luke can imagine they'd be a big help. Coming from a big fight sounds familiar, too. The replica's gaze lowers, just a bit.
