Plot hole: Emma is getting people to sign a petition to get tampon machines in the girls' bathroom. But in the episode "Mother & Child Reunion," when Joey and Caitlin are in there, there's a tampon machine. So you can see that they took it out or just neglected the fact to support the plot of this episode.
