What a Gas

Batgirl roamed the halls of this empty building lit up only by the glow of the moonlight coming through the windows.

"Quinn!" Batgirl called out loudly. That prompted a stack of papers to fall off of a nearby desk, a rat then scurries across Batgirl's feet, causing her to jump back right into Harley's waiting arms.

"Scaredy bat!" Harley places a gas mask over Batgirl's face. Breathing in, Batgirl's becomes dizzy and falls ****.
