Birkhoff & Harley I sleep where I want, when I want, with who I want. Inside Harley was a girl wanting to be free. And here she was, free of the Joker. Granted, she was just attaching herself to other men here (well, at least Merlin). But she was doing what she wanted. And she found herself attracted to Birkhoff. She couldn't explain it. It probably all boiled down to how careful he was with her when he was checking the bomb. Nice guys don't always finish last.
