Some ideas I have bouncing around my brain at light speed:

Dream chasing after Nightmare while breaking apart

The idea that all the Bad Sanses had a crush on Grillby at some point as Classic and totally DON'T still have one

Sanster but, like, Gaster is legitimately crazy and Sans is his babysitter keeping him from going completely off the rails on the Core project (Asgore begged him, please Sans he can't stop getting complaints about his royal scientist causing explosions and he refuses to be fired-)

My Variant Cross whimpering to himself because XGaster won't stop taking over his body and demanding that they start conquering AUs again (a whole Jekyll and Hyde situation)

SansterWeek2023！

Day 1 STATS/MEDICINE

It was after taking the medicine and then sticking the patch that detects body changes on the soul, it should be both choices are occupied XD

Referenced a paragraph in a Sanster article on AO3: Mix up at the Lab, Gaster wanted to give Snas medicine to adjust his body, but he mistakenly gave him a medicine that would make his bones heat up, at this time he didn’t notice Sans’s change, and gave his soul a patch that detects body data or something…
