Betty and Star
"I didn't have another prom but I did go to the Blood Moon Ball not that long ago." Someone would tell her eventually that Star was always like this, really energetic and strange, or she'd get to know it by talking to her more than once.
After switching the wand to the other hand and tucking it in her belt Star shook Betty's hand. "Star Butterfly. Nice to meet you, and it's a good first impression of the place to get to come to a dress up and have fun dance. It could have been switch genders week or something instead."
