The apocalypse has come, and archangel Gabriel (列) came down from heaven with his list (列) of people who are accepted. In the elevator's bathroom (e4) he tells Li Qingzhao (li) that she's on his list, and he tells the wicked witch (歹) that she's not. The wicked witch freaks out and takes Li Qingzhao as her hostage holding a kitchen knife (刂) to Qingzhao's throat.

Mnemonic symbol: a nation's flag. Let's say the Chinese flag.
In the observatory's kitchen (o2) Gitta Giraffe (gu) is practising her ballet performance. She got a whole crate (囗) full of jade bracelets (玉) and flags (国) and fixed one flag to each jade bracelet. This makes a perfect combination for throwing the ring with the flag waving behind it and catching the ring again after a few pirouettes.
