The infamous (between my friends) scene in my AU a long time before Frisk falls down again, 8 days after Asriel's 12th birthday, waking up enthusiastic about the day, having optimism, only to walk towards the mirror and sees himself with horns, which shoots him with a wave of dismay and passes out for half an hour. Not how I would want to begin my day.
Toby Fox for original characters. I have wanted to animate this scene for so long, and I did. An inside joke between me and @PoppetScratch
