舍己

舍 = 人 + 舌 : Mnemonic symbol: a pawn who is abandoned to save the king.

Neanderthal Man (人) is so hungry that he opens his mouth, sticks out his tongue (舌) and is about to devour Sherlock Holmes (sh) in the elevator (e3), but Sherlock Holmes acts quickly enough to throw a pawn (舍) onto Neanderthal Man's tongue so that he munches the pawn instead.

This character looks like a butcher's hook. In the space station, Joan of Arc wants to conduct an experiment about a sixth order chaotic pendulum. First she hooks a butcher's hook to a sickle, then sticks the sickle's end into a flute, and finally hooks the handle of a shovel into the last hole of the flute. She then swings the chaotic pendulum to observe its behaviour.
