順序數

顺 = 川 + 页 : Sheldon Shrimp (shu) witnesses a creek (川) forming in the encampment's bathroom ((e)n4), and subsequently a paper (页) boat floating by. Sheldon recognizes this omen and knows that he has to follow (顺) his fate.

序 = 予 + 广 : Due to an emergency Xu Xian (xu) and Zai Yu (予) both have to leave the space station from the bathroom (Ø4) and parachute (广) back to earth. They just cannot decide on the sequence (序) of who's going first.

数 = 娄 + 攵 : Sheldon Shrimp (shu) occupied a lunar mansion (娄) inside of the space station (Ø3) although he knows that it is to be torn down. Outside of his lunar mansion the construction (or rather destruction) workers are already counting (数) down from ten. When they count (数) zero, they will start taking down the whole thing with their sledgehammers (攵).
