He had exclusive access to the vault in question, which is kept shut by the best vault door money can buy in combination with what is known as a retina scan. A retina scan—”
“We know what a retina scan is,” Ascher said impatiently.

I feel like the only way Nicodemus would feel the need to explain what a retina scan is, is if he genuinely thinks that it’s rare knowledge. I mean, I just love the idea that Nicodemus is this 2,000 year-old guy who just does not understand modern technology. Like, at all. He doesn’t even have the excuse of being a wizard; he just grew up in a time when Literacy was newfangled, and now he’s here and he’s just completely baffled by what the world has become.
I’m just picturing Nicodemus using a smartphone as if he thinks it’ll explode if he presses the wrong thing, but trying to act like he knows exactly what he’s doing and doesn’t need any help at all, thank you very much.
