I am pretty excited to see her she seems interesting and I really hope her dynamic is different with Joker than Harley's was. I'm kinda hoping she's got a darker more tragic back story than Harley as well like for her life to have been pure hell until she had a bad day and turned evil then later met Joker. As for her dynamic with Joker I'd like for her to be like Shego from Kim Possible. I know them doing that would be going backwards with Joker's character but I'd like to see him be his old mischievous clownish self from time to time and I'd like his relationship with Punchline to stick out.

Essentially this is the kind of dynamic I'd like Joker to have with her if she sticks around
