He was tired.
Tired and feeling so much older. Even the little things, like a trip to the pyramids, they seemed to be routine. Well, as routine as anything in his life could be.
He was getting too old for all this running around nonsense as well, he decided. All the same, when you infuriate a giant half-mummified Child of Osiris, you learn that no matter the nonsense of running, it's really sort of the most important thing.
Soooooooo, down the corridors (always corridors!), around a few turns, leaping over the archaeological trays that were lined up along the sides of the walls. Great, that probably meant people he'd have to deal with, try to convince them to run, too...
