I think Reaper sometimes notices unusual things near Geno, for example, heat from an accidental touch, in this case, steam from a temperature difference (Reaper is not as warm as Geno, so it must be very cold for steam to come out of his mouth) #Undertale #Genosans #Reapersans

old crosspost on my mind again 🩵💜 AU where errorink is new to existence. their spaces combine and result in a long glass pane between them. they're unable to hear or reach the other, so their only means of communication is writing & drawing. ✒️ #undertaleau | #inksans | #errorsans | #errorink

✨ one of us ✨ #royaul Happy for them 🥺🥺🥺
