She didn't keep her promise
omg I don't know why I spent so much time on this, this is terrible... i shortened the original dialogue so I didn't have to draw them so many times. i kind of just had this idea that Lily was always made fun of at muggle school for showing random spurts of magic in a classroom, like Harry was. and Snape would sit outside all day and wait for her while she was at school, haha.
if you don't think snape ever popped out of random bushes at Lily, you are wrong. he did. i asked him.
