As Joker was leaving the store, two feet swung into his line of sight, aiming for his chest. Effie, currently Sparrow, had heard the commotion and took off for the store, eager to get some action, not realizing who was committing the crime.
A fact she regretted as she flipped to a low crouch, pulling her long bo stick from her back, her face paling in fear as she looked up at the Joker's face. Oh...she was fucked.
She spun the staff, slapping one of the henchmen with it twice, both coming and going, sending him to the ground, tossing a smoke bomb at another's chest, keeping an eye on Joker as she tried to take out his men before dealing with the Clown Prince of Crime himself.
