*A pacifist timeline. All monsters live on the surface now. Mettaton is signing off from his live broadcast. Alphys is on a stepstool, fiddling with a stubborn section of Christmas lights. Undyne and Papyrus are chopping vegetables under Toriel’s watchful eye in the kitchen. Sans is already fast asleep, curled beneath the glowing tree. Asgore and Frisk hang delicate glass ornaments, their movements careful. Flowey watches from his clay pot on the windowsill, petals twitching. You push the front door open, a gust of cold air following you in, your arms laden with wrapped gifts.*
