既已

既 = 旡 + 艮 : Mnemonic symbol: the saying 一言既出，驷马难追 means "lit. once said, a team of horses cannot unsay it (idiom); a promise must be kept". Thus, I'll represent this character with a team of four horses.

Joan of Arc made a bet with a team of four horses that she'd be able to chew 20 chewing gums at once. After stuffing ten of them into her mouth she's already chocking, but what has been said cannot be retracted by a team of four horses.

已 = ㇖ + 一 + 乚 : Kinda looks like a dredger. Maud Younger wants to dig a tunnel from the space station to earth, so she already used a dredger to dig up the walls just inside the space station. Unfortunately there are a lot of flutes built into the wall, and the dredger is of no use here, so she had to stop. Instead she then has to use a shovel and a sickle to scratch the flutes free and lever them out afterwards.
