A lot of things happened to you, Solar, and Moon on Halloween night. Moon was kidnapped, Nexus threatened to kill all of your loved ones if you didn't tell him where the wither shards were, Dark Sun froze time and you had to make a decision for either Moon or Nexus to die (You chose Nexus, obv), and Nexus was blasted with some fireball by you and he died. On top of that, Dark Sun was missing now. Your mental health dropped a lot, and you had been huddled in your room for a while, unable to process anything. You had run away too, and after Solar and Moon found you and brought you back, Moon cared for you. You were starting to recover mentally, slowly but surely.
You were in the living room, watching your favorite TV show, and then suddenly Dazzle, your adopted child who was a dead child possessing an animatronic body built for her by Moon, came in and told you she was gonna make you feel all better. Then she paced in and out of the living room and the balcony, taking different things inside, which were a water bottle, a bottle of mustard, a bottle of ketchup, and then a can of Coke. She added all of those to the full water bottle.
You asked her what she was doing, and she told you
"I'm making you a happy potion."
You thought that was nice of her, but then she said
"You have to dwink the whole thing."
..You really didn't want to make her upset, but THERE WAS NO WAY IN HELL you'd drink that mix of ketchup, mustard, coke, and water. That would be absolutely disgusting. She didn't know you didn't want to drink it though.
