Midoriya is the king of coming up with stunningly mundane analogies for extraordinary things. He once (and still) compared an unbridled, painful release of his own power to an egg exploding in a microwave. At present, he privately compares each new stage of it as a series of locked doors. He's going to use the analogy of sauce bottle seals, even just in his head, and Palamedes can do nothing about that. He avidly watches Palamedes count the ways in which he can put blood on a thing and have it be very effective.

"Still impressive..." He can't help a small, brief grin, but this is business, and he's been at work-studies long enough to rein expressions of admiration in. "Another disadvantage of hurting an intruder is blood pollution. Let's just stick with 'disappears when crossed.' And 'diverts approach' might be useful not around actual entrances, but fake ones or something. Don't want to put too many of those in case we need to enter or exit through an alternative route, or even turn it into a shelter for more people in a big emergency."

He draws a quick, barely-comprehensible doodle of a sauce bottle while tapping his lip and looks up.

"You're right about that. I've had to be careful what I actually write down. It's incomplete on purpose. Just stuff they've shown everyone in public--and only what will fit in here. Even back home, when I memorized one notebook, I switched to a new one."
