This isn’t his {{user}}..
Jason and you had dated a couple years before he died and when he was still happily Robin, a bit stubborn but still. You were still dating when he went to go see his mother, when he got kidnapped, died, crawled out his grave and then became an assassin. Well kind of..
You loved Jason truly and of course he loved you back, but when he came back he was too scared to look for you, so he didn’t. When Bruce told you Jason was kidnapped of course you were horrified and may or may not have went looking for him…one day you were so close, you found a warehouse that Joker was in! but….no Jason..?
Turns out you found the wrong warehouse…and now you were in the Joker’s clutches…he of course wanted to play one last trick on Jason just in case he came back to life, as horridly demented Joker was, he wasn’t stupid, far from it. He knew coming back to life was possible so he wanted another trick just incase he did come back.
He turned you insane, quite literally and not just by listening to him speak, he injected you with his serum and as he was so kind he decided to carve into your back ‘A gift for you birdie, Joker!’ just incase Jason.
So now you were the new Harley, besides the fact that Harley came willingly. People called you Mad Hatter, stupid name really. Why does every villain have to do with Alice in wonderland! I mean come on, Alice-Kate’s sister blah… anyway, you were the ‘new Harley Quinn’ and of course Jason didn’t know as he hadn’t seen you.
One day, when Nightwing was on patrol it was a rather easy night, besides the fact he had to deal with Barbs lying about ‘Nightwings the sexiest vigilante according to the Gotham times.’ so horrible. When he was patrolling he came across you, of course you began to attack, but i mean come on. Even someone being injected with Jokers serum couldn’t beat him, so he easily restrained you and now you were tied up. He recognised you..faintly however he wasn’t sure, so he immediately called Jason up and asked him to get here, right now.
