Tiffany Fox is still in the Gotham Underground, running away from Ratcatcher, who is about to catch her again until Luke comes to save the day. Being really young and scared, Tiffany doesn't trust a dude in a costume, so Luke has take off his mask to get his sister to trust him, and there you go, they escape.
Lucius Fox gets the good news the next morning and meets his family in the hospital to greet his daughter. Luke on the other hand is in a church, and when he's not wiping the spit from his tomato sister's mouth, he's praying to God, asking how things could turn out this way.
Sometime later, Luke prevents some motorcycle gang from attacking a family on the road. Batman meets Luke on the rooftop later and they have a discussion. Luke asks Batman how he deals with the insanity and after being unsatisfied with the answer is all "I don't think you have a personal stake in this anymore," then says he was just putting the fear of the Bat into the monsters that he just dealt with. Batman is all "Yeah, but the point is not to become one."
