Harley flashed a brilliant and very heart felt smile at the Doctor's antics. Most people would have at least blinked at mention of someone being a kitten but since Harley knew a 'catwoman' as well as a plant lady, she was willing to take everything at face value.
She was just beginning to think things might finally be looking up for her when a certain very familiar chilling laugh rang out in the cafe.
For a split second Harley was torn. Should she grab a bottle from the bar, break it and go after the Joker's throat with the broken glass or hide and hope he went way quickly.
A sudden mental flashback of constant beatings while the Joker laughed hysterically at her pain decided her.
Leaping over the bar to the side where the Doctor was standing she crouched down and even though she hated herself for it, she trembled violently as she peered around the edge trying to spot the murderous clown.
