So, Sans, when did you find out Frisk was your soulmate?
Sans sweats a little, pulling at the collar of his sweater.
“…she was eleven. i, uh… didn’t like ‘er much, when she was runnin’ around, changin’ monsters’ minds ‘bout tha war and killin’ humans and shit. kinda figured her for tha kinda human we’d been taught ta hate. the kind that hated us too. figured she was jus’… lullin’ us, honeyed words… that stuff. …when she made it ta tha judgment hall, i was waitin’. had watched her spare ‘em all, every single monster that had tried ta kill her, over and over. i didn’t understand. i was pissed. who did she think she was, huh? stealin’ our war an’ our freedom by livin’, refusin’ ta give it up and die already. the others, even my bro, were too soft ta do it. they all became friends with ‘er. she tried it on me, too. ‘let’s be friends, sans,’ she said ta me. ‘we don’t hafta fight’. …i killed her. right there, with a smile on mah face.”
He fell silent, looking away and clutching at his chest.
“…killed me, ta see her soul shatter. literally. felt tha connection, moment i saw it. an’ watchin’ her die, knowin’ it was me that killed her? my soul split. thank tha fuckin’ stars for resets.”
He chuckled ruefully, shaking his head.
“she didn’t like me much neither, after that. wouldn’t talk ta me for months. wouldn’t offer ta be my friend again for years. i tried ta make it up ta her. stubborn woman… stubborn, beautiful, smart woman… i’m real fuckin’ lucky she decided ta stay. that she thought more a us than we deserved. otherwise… i’da never seen her again. wouldn’t have my angel… wouldn’ta had her. nothin’.”
