The text in the upper-left says, “Nerv Headquarters: Central Dogma B20”.
Misato has written, “This area!!”
Misato:“I was sure this was the right way.”
She lowers the map and a door opens.
Woman:“Central Dogma's…”
Reichu: “CAUNTION”! Engrish alert!
MDWigs: That's a nice transition there, with the shape of the floorplan being a hexagon and then the corridor they are in also being one.
Sharp-kun: Hexagons and octagons seem to be recurring themes.
Shin-seiki: It's a little amusing to note how this map, and the fact that she immediately gets lost anyway, indicate what a n00b Misato herself is to Nerv HQ. (BTW, WC = Water Closet, i.e., lavatory.)
Hexon.Arq: It'd be nice if that map had a compass on it, at least. Of course, this way, someone who finds it in a dumpster somewhere won't be able to make heads or tails of it, and that's good.
