Not seen afterwards of episodes
Gretchen is seen doing various disgusting things, including digging in her nose, scratching her armpits, spitting, and popping her zits at lunch. Also, she randomly takes a bite out of Quinn's apple, grossing out Lola, Quinn, Michael, and Logan, but Chase does not seem to notice. Wanting to believe her to be just like Zoey, he eventually admits the truth that he misses Zoey and is in love with her, too.
Despite the similar appearances, Gretchen and Zoey are exact opposites.
