Joker had gone insane, then you met him, and he made you just like him, all while falling insanely in love with you

He was insanely in love with you, long story short, he threw you under the bus so you got caught and thrown in a maximum security prison. He was willing to take the whole thing down to get to you, he was going even more insane without you, so he and his men invaded the prison, blowing up any cell you weren’t in “I know she’s here! Find her!” he barked to his men.
