No one needed to know that she'd intended to let the tiny birds out of the big, scary prison.
No one needed to know that taking the paying job to let the three bloated businessmen out of Blackgate was just a cover, a way to maintain appearances.
It had been a silly weakness, a silly plan. There wasn't any profit in it. It was sentimental, and the kitty cat had given up being sentimental years ago. She'd learned the hard way that sentiment only hurt in the end. And, regardless of what Eddie said, she needed to remember that this Gotham was just a smaller version of the one she'd spent the past seven years in.
In the end, this one would hurt the same way and leave the same scars. And the kitty cat didn't need to go through that twice.
So, she pretended.
She pretended that she'd never intended to help the little birds. And she pretended that the familiar shape saw sneaking around the prison wasn't the reason for her abrupt departure. She pretended that knowing Bruce was there hadn't changed her plans. She left her weakness at the grate she'd been intending to crawl back through.
She took her money, ands she left.
Just like in her Gotham, they didn't actually need her here; it was a biting reminder.
It had been the hardest thing to get used to, once she'd found herself home. Before everything had changed, she'd distanced herself from the Batfamily here, in this Gotham, but it had only been a surface thing, a facade. She'd still known everything, because Bruce had told her everything. But there, in her Gotham, there she wasn't involved in anything at all. There, Damian had died and she hadn't known for months. She'd only known that the Bat was hiding, and when she'd dragged him out of hiding with her bad behavior, she'd thought it was because of Joe. Good old Joe, who'd been causing so much trouble.
She'd only learned the truth months later.
She had learned to live in that place, to survive there. She needed to remember. She couldn't afford to forget.
She wouldn't forget.
She took her money, and she sent a courier with Eddie's share. He might have joined the team of heroes, but she hadn't; she'd pay her debts. She was there, walking free, because she was supposed to bring down that team of heroes, and it wouldn't do to forget that.
And if Gotham was falling, it wasn't her job to stop it.
She opened a Door, and she crossed back to Vegas, and she didn't look back.
