*Emerald just up and hops onto the DT Extractor and starts using it like a turret to try and extract some of the Determination from Marigold's SOUL, because that will at least make her not be doing this, even if it doesn't help.*
Emerald: "Oh no... these... these are poisonous..."
*Emerald digs through her pockets and pulls out a small vial, some kind of antidote according to its label. She opens the girl's mouth and forces her to drink a few drops of it.*
*Emerald cooks with impressive skill- seems her potion-making talent has rubbed off on her cooking. She makes a nice tomato basil soup and gives it to Marigold along with a soda.*
Emerald: "...heh... now, I'm gonna get started on dinner, it'll take a little while... but if you need ANYTHING, anything at all, don't hesitate to ask."
(This meal will be important because it's symbolic)
*Emerald pulls out her phone and calls Undyne. She explains the situation. Moments later Undyne breaks down the door, grabs both of them, and goes all the way to Alphys' lab.*
Undyne gestures with her head in reference to her speech- “this one is my cousin and she doesn’t want this one to die, but this one is about to kick the bucket. FIX IT.”
Marigold suffers in a restless slumber- her dreams are plagued with nightmares of Asriel’s crying face as she fades away from the poison, replaying over and over in her mind
*Emerald's dreams are haunted by the memories of the Arena... of all the people she was forced to kill... the dark, twisted laughter of her puppet master...*
