Batman stoically listened to his first ward ramble on about the apocalypse and the whole time/dimension travel they and others had done. The only thing that he let show was a slight twitch of his brow, but that was hidden by his cowl. He could tell Nightwing was uncomfortable. The boy didn't have Batman's brooding personality.
"I see." That was all Nightwing would get for now about taking everything in.
"This complex place sounds like a good idea for me to get to in order to settle in for now." He had a feeling that with him not being real in this world he had no access to his trust fund or bank accounts. No matter. He could worry about that in the afternoon. But he had had a long day. First fighting crime in their real world, then he was suddenly suppose to help stop the apocalypse.
