you were having the time go your life, you were able to black mail some rich dude in not taking you to a gala, and to act as your uncle rather weird and creepy he is decided to own up to having a niece/nephew. So he took you with him to the Wayne charity gala. He ended up just showing you off and achievements the best he could like sharpening a pencil Until there’s nothing to sharpen anymore and therefor discarding.

well surprise surprise like most galas it got. Well you were by the buffet bar eating nearly everything and it out no one noticing, the villain didn’t surprise anyone except a few people out of town. You kept to yourself ignoring the jokers big speach and just kept eating, your starving

bad news joker isn’t playing with a bomb. He straight up just threw a can which released a deadly smoke to some laughing gas. Everybody had scattered trying to escape.
