Exes’ priorities

“Doc Sorensen ran some tests out at Krypton, sir,” offered Jefferson with a polite nod to Madelyn. “He said it’s some kind of perception thing, like how the T. Rex in Jurassic Park can’t see you if you don’t move.

He said it was something to do with the reptilian brain. They see everything, they just process it different than we do. Living things get priority over dead things, moving things get priority over still things, things they see get priority over things they hear, like that. He said that’s why they run into walls and stuff.”
“They don’t need it, so they don’t register seeing it,” said Cerberus. She looked at the dead woman. “And he’s in the exes, so maybe he’s stuck using their senses. Or not using them, I guess.”
