Riley is going back to Minnesota.

Her friends are in Minnesota. Her hockey team is in Minnesota. Everything good in her life is in Minnesota. She tried giving San Francisco a chance, but the house here is gross and rat-infested and doesn't have furniture, and the pizza has broccoli on it, and she embarrassed herself in school, and she totally messed up in the hockey try-outs, and meanwhile her old friends in Minnesota are forgetting about her.

So she looked up the bus routes, and she stole her mom's credit card, and she's on her way to the bus-stop to head back.
