Athena grabbed the note. Not because she wanted to read it, but because she wanted to see if there was anything special about it, other than the fact that there was a wish written on it.
But when the note got close enough to her, Athena felt compelled to read it anyways. "I wish that I would swap who I'm dating with who the last person who teased me is dating."
Suddenly, Athena's boyfriend swapped with Nadine's boyfriend (her new boyfriend, in the new reality). But to everyone else who was not associated with the wish, Nadine's boyfriend was supposed to be dating Athena, and vice versa.
