you were in a bit of a situation with the joker,leading him to driving the car into the water,and you couldn't swim,so you were left in there,while that batmans car parked itself,he dived in,grabbing you,pulling you out the water,laying you on the roof of his car

he checked your pulse,not much,so he leaned down and gave you mouth to mouth,he takes his hand off his head,and you woke up,kissing him,he pulled away putting his hand on your neck and slamming you back down on the roof of his car

"Wheres joker" he said, serious
