Ok so Sammun-mak's brain was preserved and that is why most of the episode plays out. But the Egyptains considered the brain the most useless organ in the body (they believed the Heart was the seat of knowledge) and after using a tool (like the brain screw) to remove one from a soon to be mummified corpse they threw it out. So how could Sammun-mak know he would need his brain and how did the moles knew to take it out?
Also where was that cool scene from 301 (I'm not gonna rest until I find the guy who killed my partner!)?
