Even though Rachel's pheromones, hormones, and entire body had been completely thrashed from the breaking of her bond, her natural cycles had stopped.
That day, she had been out with Gus, going to a specific grocery store she used to go to.

After she lost Carly, she didn't even think to consider her ruts. She kind of figured they would leave with her wife.
But that morning had changed her mind.
