Damian tripped and fell into a vat of acid

Damian took some solace in hearing Selina say that she wouldn't let him fall. It would be her head on a pike if anything happened to Damian on her watch anyway. His father wouldn't be very forgiving if he learned his own son was boiled alive while out assisting Catwoman in her antics. His reassurance was dashed when he tripped on the jagged metal catwalk with the heels his new mentor insisted he wear. They were "a part of the outfit" she said. It would be fun, she said. Damian instinctually reached for her belt as she fell over the ledge only to find that instead of her standard utilities, all she had was a makeup pouch and a whip.

Out of sheer desperation, she lashed the whip out towards the railing as she fell.

"Selina!"

Damian called out her name as the pink hue from the boiling acid beneath her reflected off of her skin. She clung to the whip's handle tightly, managing to wrap it around the safety rail. Catwoman pounced into action, leaping to the whip and grabbing onto the long end to attempt to reel Damian in.

"Don't worry, I've got you! Just don't look down, kid!"

Selina tried to remain calm. She'd lost her sensual composure. Behind all that makeup and kleptomania she wasn't evil. She couldn't just let a kid die. Much less the son of her lover.
