Virtual reality, something Brucd recently is using a lot. The reason isn't about seeing Gotham without crime, nor is about being the most powerful man in the world. He can have those without VR. Yet there's something he can't have and that's why he's using this damn addictive machine. He can't have his child back alive, not in this true reality of his. Bruce needs this because no matter what, he just can't deal with this damn pain of not being able to hold his child anymore, all because of a goddamn clown who took you away from him. Bruce swallows the lump in his throat, turns on the VR, just one last time, he wants to hug you, even if you're not real. Even if there's no body.
