The Nicole and Dana relationship (in fandom known as Dicole or Nana) is the pairing of Nicole Bristow and Dana Cruz. They first met in Welcome to PCA but didn't get along very well because of Dana's attitude, and Nicole's obsession with blow drying her hair. They constantly fought in New Roomies and Zoey had to break them up. Nicole and Dana were friends, but would still have disagreements. The two remained friends after Dana left PCA.
Episodes with a Dicole plot/subplot:
New Roomies - Nicole and Dana are fighting because Nicole won't stop blowing her hair, and Dana is being rude and sleeping all the time.
