二虎相斗，必有一伤

二 = 一 : Mnemonic symbol: a capacitor, because the two strokes remind me of the symbol in electrical drawings. Albert Einstein (Ø) is experimenting with a capacitor (二) in the space station's bathroom (Ø4). He finds that it's uncomfortable to discharge a capacitor using two flutes (一).

虎 = 几 + 虍 : Helga Horse (hu) is trying once more to get some nice stripes (虍). This time she is lying on the tiger's (虎) small table (几) to have him tattoo the stripes on her body in the space station (Ø3).

相 = 木 + 目 : I take "eye" and "tree" as resembling an ent, an alive tree. Marie Curie portrays an ent in the anglepod's bathroom. Unfortunately she's really bad at painting, and her portrait resembles more a Christmas tree. The Eye of Providence enters and, just from the shape of the Christmas Tree, instantly recognizes its own portrait. The Eye of Providence asks Marie Curie how much she wants to have for the painting, but Marie Curie just wonders if the Eye of Providence is made from Radium, because it radiates so much.

斗 = ⺀ + 十 : Mnemonic symbol: a 斗牛士 (dou4 niu2 shi4) is a matador, who will represent 斗 when used as component.

The matador (斗) and Don Quixote (d) are fighting (斗) in the outhouse's bathroom (ou4) about who may use the bathroom next. The matador yields a holy cross (十) as a weapon, while Don Quixote (d) wisely chose a blossom (⺀) to cushion the crosses' blows.

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.

伤 = 亻 + 𠂉 + 力 : Sherlock Holmes hurt himself when he got struck by one of the traps in front of the anglepod. Luckily Rosa Luxemburg passes by: she has the key to unlock the power button of the trap system and turns it off, so that Sherlock can free himself.
