Oh, my my my, Harley Quinn. She really is the ultimate little.
She does anything Joker wants, anything he needs, without a second thought. She is his puppet. Harley loves just being able to be close to him. To get deeper into it, she gave up everything, consensually, just for the chance to be with him. Her career, her reputation, all of it! And nothing was guaranteed with Joker. She knew he was legit crazy pants, and she went for it anyway.
This girl really LOVES her Daddy. She is her Daddy’s Little Monster.
And I, for one, love her even more for it.
