the idea has some variables we can figure out together but! basically they were secretly something during/after filming lemonade mouth and it was a very popular ship amongst the lemonade mouth stans - like, they had a ship name and were the lesbian/queer zanessa of that era for disney channel fans, fully discussed and dissected on fan forums for a pretty long time. it was never confirmed or addressed because that was very much not a thing they were allowed to do at the time, but naomi came out in 2015 and that's when the rumors reignited which could cause trouble for them and wherever they stood then/presently!
i don't have any faces in mind tbh so whoever you feel fits or i can try to come up with suggestions!
