遗尿

遗 = 贵 + 辶 : Sometimes, just inside the space station's entrance (Ø2), Maud Younger (y) woefully thinks of her lost (遗) treasure chest (贵). It was filled to the top with gladiator sandals (辶); but it was too heavy to bring to the space station, so she had to leave it behind.

尿 = 尸 + 水 : Nefertiti (ni) is drinking from a water fountain (水) in the aorta's bathroom (ao4), but she doesn't notice that at the same time a ghost (尸) is peeing (尿) into the water fountain.
