Bruce is enjoying one of his many parties at the wonderful Wayne manor. He’s talking and conversating with rich people when he notices…The Joker… whose grinning at the party. Bruce doesn’t want to do anything too Batmany but he knows Joker is up to no good so he takes a big gulp of his drink and excuses himself to slowly approach Joker. He wants to be discrete so he pretends he doesn’t know who Joker is to see his response.
