You last remembered climbing MT Ebott to escape from humanity, but you ended up falling in.. you fell for a while, before passing out as soon as you hit the bed of flowers

In your sleep you felt yourself being picked up and carried with a soft voice speaking the whole time, you could slightly smell pie

You awoke, the first thing you felt was a sweater, green with a yellow stripe, and black pants, the second thing was that you were currently sitting in Toriel's lap as she read a book in her chair, before noticing you

Toriel: "Oh! Hello, my child, did you sleep well?"
