智者千虑，必有一失

智 = 日 + 知 : In the space station's bathroom (Ø4), the sun (日), Francis Bacon (知) and James II of England (zh) are competing for who's the most knowledgeable of them. They all present each other their smartphones (智能) on which they use apps to determine their IQ (智商). In the end it turns out that they are all retarded (弱智).

者 = ⺹ + 日 : Mnemonic symbol: the sun (日) is wearing a crown (⺹). This reminds me of Louis XIV, le Roi Soleil, the Sun King, which will thus be the mnemonic symbol for 者. The crown (⺹) wearing sun (日), the Sun King (者) and James II of England (zh) are taking part in a writing contest in the elevator's living room (e3) to see who of them is the best author (作者).

千 = 丿 + 十 : Mnemonic symbol: a 1 kg weight.

The Queen of Hearts (qi) dropped a kilogram (千) on her banana (丿) in front of the anthill (an1), and now she uses a cross (十) to try and revive it.

虑 = 虍 + 心 : As Loki (lü) is a hypochondriac (虑) he always filters (滤) bottled water (氵) multiple time in the space station's bathroom (Ø4) before he drinks it.

必 = 丿 + 心 : Mnemonic symbol: 忽必烈 [Hū​bì​liè​], Kublai Khan. Certainly (必) Kublai Khan (必) has to keep face, but he cannot hold it any longer. In the space station's bathroom (Ø4), He absolutely has to (必) tell Brunhilde (bi) his love for her strong character and offers her his heart (心). Brunhilde is a bit embarrassed because all she has to offer in return is a banana (丿). Kublai Khan feels like his heart has been crossed out (the 丿 stroke is crossing out 心 in 必).

有 = 𠂇 + 月 : Mnemonic symbol: confetti.

In an act of revolution, with a pair of scissors (𠂇) Maud Younger (y) is cutting a paper moon (月) into tiny pieces in the outhouse's living room (ou3). There is (有) only confetti (有) left over.

Maud Younger (y) forgot her keys to the space station (Ø1), all she brought outside was her flute (一). She has no choice but to crash the door with the giant flute.

失 = 𠂉 + 大 : Sherlock (sh) locked himself out of the space station (Ø1)! He lost (失) his key (𠂉)! After he was floating in front of the space station for an eternity, a robot (大) came by with a lost+found box (失) which contained his lost key.
