Sans always catches on quicker when they start acting off-script, or let little hints of future history slip out without meaning to. He never does anything, but they can feel the sharp snap of his gaze in that flinching moment, and in all honesty they can't exactly blame him. Frisk may not be the one initiating it all, but it's still their fault the loops are happening in the first place.
