Haha, awesome story! I love that the first half was all dialogue. Great way to get the situation across without quite expositing on it.

Keep on writing!

Um...what exactly is this a crossover of?

My reaction upon seeing the summary: "Oh, God, she didn't!" Seeing that Riley made the wish to move to San Francisco: "She did!"
