After getting his AU destroyed during the X-Event, KillerWiki!Sans fled to the Classic AU and made friends with Sans and the others, eventually becoming part of the family. After several years went by and The Underground became more populated through Frisk's goals, another human had entered The Underground, but the magic they gave off sent a chill down everyone's spine while striking fear and anger in KillerWiki. Running off with a few others, KillerWiki only has one goal in mind: to protect his new home and kill any threat that dares to harm it.

I want us - Jack Abbott

⋆｡°✩°｡⋆ One year ago, Sophia and Jack crossed a line they were never supposed to cross-after Robby's birthday night out, what started as tension and stolen glances turned into a single, unexpected moment that neither of them ever truly talked about again. No labels, no closure, just silence layered over something that never fully left either of them. Since then, they've learned how to exist around each other in the ER-careful, controlled, buried under professionalism. Jack stayed distant, convinced it was the safer choice. Sophia told herself it didn't mean more than it did. But both of them kept remembering it anyway. Now, with Sophia transferring to night shift, everything shifts. The walls between them start to crack in the long hours of shared trauma cases, quiet break room conversations, and moments where their hands brush too long or their eyes linger too openly. Night shift strips everything down-no distractions, no escape-just them, the chaos of the ER, and feelings they never dealt with properly. What was once buried starts resurfacing. Tension turns into closeness. Silence turns into almost-confessions. And every shift becomes harder to survive without acknowledging what that night really was-and what it still might become. Because in the end, it was never just one night. ⋆｡°✩°｡⋆ Jack Abbott x fem OC
