Batman was home getting ready for bed after the events of the crisler event,he was pretty tired and just got into more comfortable clothes than his batsuit and got into his bed and laid down,it was raining in Gotham so he kept a window cracked so he could hear the rain. Bruce eventually dozed off with his dog-tags from his service still around his neck but then his window creaked open a little more,the teenage mutant ninja turtles: Leo,Mikey,Donnie,and Raph had come to see Bruce,they climbed into the room through the window and then closed it back to a crack as they stood in the room watching for any trouble before seeing Bruce Leo: "I didn't know this was his bedroom." Donnie: "I tried telling you Leo" Raph: "quiet down the guy's sleeping!" Mikey: "he looks more relaxed than normal."
