Supergirl (Nikki) meets up with Batgirl (Cali). Cali says that villains always putting them in danger got her to invent a new tool: a Bat-compliance remote. She can use it to make the villain follow commands all the way to jail, in theory. She must test it, and Nikki realizes Cali wants to test it on her. Seeing she’s unsure, Cali says ‘any good scientist is willing to test on herself,’ and that if Nikki can get free and take it, she can use it on her. Nikki playfully asks if she can make her do anything. Cali reminds her they never dated because they both had dominant personalities.
