10 Things You Need To Know About Margot Robbie's Harley Quinn

9. She Feels Guilty Over The Death Of Jason Todd

That scene they were shooting for Batman v Superman was apparently the murder of Jason Todd/Robin by The Joker. Harley wasn't present for that in the "Death In The Family" comic book, but rumour has it that she will be in the DC Cinematic Universe and that it's going play a huge role in how her relationship with The Joker plays out when she joins Task Force X. Harley apparently feels so guilty about Jason's death that she will be estranged from The Joker when she's introduced in Suicide Squad. That contradicts reports that Harley is captured by Amanda Waller when she tries to free The Joker from Arkham Asylum, but makes sense. After all, her guilt will no doubt help the audience to connect with the villain. This flashback will be triggered when Batman looks at Jason's Robin costume on display in the Batcave, and it's been said that the Red Hood is a big priority for Warner Bros., so Harley might not have to feel guilty for too long if he'll later return as that fan-favourite vigilante.
