"undertake" is a prompt i would prefer to take in two ways so here ya go
femslash february #24: chlolix (undertake, dusk)
it's night. alix is digging up a grave - a recently occupied one, by the looks of it. there's no gravestone, there's still a mound of earth, and she's moved aside a lot of flowers and banners and lights to be able to dig. she digs fast, but she does take care to gather the dirt, and nothing has been destroyed or taken - yet.
suddenly, her spade hits something hard. she breathes out, and says into the empty air: "yoo-hoo, bitch." she keeps digging, stabbing the spade into the coffin repeatedly; she clearly doesn't care to preserve it. after half an hour, the soil is cleared enough, and she jabs the spade hard into the wooden lid; it cracks, then breaks on the second jab, and she leans down to lever even more wood off with her hands.
suddenly, though, an arm juts out of the coffin and grabs her by the wrist. alix grins, but bats the arm away. "gimme a minute," she says.
"hrmh," says whatever is down there.
it doesn't take long until the lid is completely broken, and alix stands broad-legged on the coffin's side, towering over... chloé bourgeois. "didja miss me?" she says. "bitch?"
"ugh," says chloé, and reaches up her hand again. alix grabs it and pulls her up. "you're so crude."
alix smirks. "i saved you, didn't i?"
"i saved myself. you only finished what i started."
they start to get to work, chattering the whole time in low whispers. the shattered lid goes back in, then the dirt - alix handles the dirt on her own. but chloé handles the decoration afterwards, putting the flowers back so the grave looks even prettier than before. alix grabs chloé's hand, and chloé secures the grip. and then they escape.
(explanation, given through dialogue: chloé, who managed to piss off someone important, had to fake her death to avoid sleeping with the fishes. alix, her girlfriend, dug her out the night right after her burial ceremony. they're now leaving for somewhere less hostile - like new york.)
