Echoes what-if prompt! I don't know if this will work since we don't know how Sans will wake up yet, but this idea has been stuck in my head.
So far Sans has been mentally incapable of recognizing the truth of his situation until he couldn't escape it with Papyrus being abused. Not just because he is in denial but his own health and mental stability depend on it and he is at risk of falling down.
The what-if situation is that after he passed out from attacking Taylor, his mind finds a way to rearrange the situation and his memories to help save his life. So when Sans wakes up, he recognizes Y/N as being his loving girlfriend and Taylor is the awful roommate.
It's not that he thinks Y/N is Taylor but his mind swapped them entirely, so his mind just fills in the gaps by changing his memories just enough. Something like:
- Taylor is this horrible roommate who has been blackmailing him about the machine but 1 year ago she invited the lovely Y/N to move in and she and Sans started dating (up to you of Sans thinks she's dating the other skeletons or not).
- Sans has been working hard on the machine to fix the situation and end the blackmail but his darling Y/N takes care of him, keeps the house in order, sending Stretch to deliver food him she made, and she was finally able to convince him to talk with Papyrus when he found out that Taylor has been abusing him.
Pretty much all of Sans' interactions with Y/N are rearranged so that he was friendly to Y/N instead of threatening. Of course none of this actually happened and Sans' mind is trying to avoid his soul shattering from the truth that he didn't protect his brother from being abused by someone he willing allowed into his home and was in love with.
So Papyrus pleads with Y/N to let Sans continue to think they are a couple, even if she doesn't actively pretend or lie about it, until Sans recovers enough of his magic and stabilizes. This would be relatively easy except Y/N being the angel she is unintentionally keeps acting like the girlfriend of his dreams. Taking care of everyone, listening to his jokes, cooking him homemade meals, being kind to his brother etc.
Cue hijinks, misunderstandings, and awkward situations.
I actually really like this and am disappointed I didn't actually do this in the fic. But I guess it wouldn't really fit with the story.
I am writing this down and will do it for an Echoes chapter though!
