Selina makes many references to “the Bat Brain” in Cat-tales. She respects it as a force of nature that it is, and relishes her ability to short circuit it with a moist whisper…
“She gestured, slowly, the edge of her fingers just grazing her chest as she traced the border of the bikini top. The mental picture this evoked finally brought about the wordless scowl she’d been waiting for, accentuated by a barely perceptible stiffening of the muscles just visible through the eye slits of the cowl… Batman’s tell, the tell which meant victory. She had, once again, jostled the bat-brain until she jarred loose any thoughts of crimefighting. That task accomplished, she returned her attention to the computer screen with a purr.”

“If you keep tickling my ear like that, I won’t be able to concentrate,” he managed hoarsely. “Please, just… this is why there’s no sex in mysteries. Just… sit over there,” he pointed. “Less Irene Adler. More Watson.” She went to the chair, laughing that, after all these years, she had finally short-circuited the great bat-brain—and at the worst possible time for Kitty’s trademark curiosity.

“It. Was. Infuriating. The woman who loved him as Bruce and the Cat who fought him as Batman wanted to know what that remarkable Bat-Brain was up to, and it seemed like he was deliberately missing the point.

I rubbed my forehead. It isn’t often I can’t keep up with the Bat-brain, but this was one of those times, and the one downside to that RAW INTENSITY that is Batman is that it’s all but impossible to slow him down.

“Look, I get that you’re upset about what happened to me this afternoon, but you’ve got to stop trying to ‘fix it’ retroactively, because you’re obviously not thinking clearly. And you really shouldn’t be out in this condition. Not if, you know, the Bat-brain is out of commission.”

“Mhm. Confessed everything. The Auchinclosses, the Winthrops, the Mellon-Scaifes, the Broadmoors. He worked it out, and what he’s personally acquired for the Orphans Fund that those people never planned to give before he turned that lovely scheming Bat-brain on them comes out to 17.5 acres of Catitat, food and veterinary care for forty rescued lynxes and—because he correctly deduced that I liked to treat myself after a heist and didn’t put every single penny into the Catitat—two weeks in St. Kitts.”

“Oh, you found a place for the Last Bimbo Hurrah?” she asked, coming closer to check out the workstation screen. He looked up at her with a raised eyebrow and she added, “Yeah, okay, that would have sounded better if I didn’t look like a Flash Gordon cocktail waitress. Forget how I’m dressed and impress me with the Bat-brain. Where are you taking Treasure and Trinket?”
