sorry about the delay! alex and ro have a very complicated relationship due to alex's father and the whole uncomfortable "blended family" situation, but ro pretends that everything is absolutely fine and they get along SWIMMINGLY because she's just inconceivably naive and avoids confrontation/rejection/negativity like the plague, but really she's just this fragile half-adult that never had to face any real conflict in her life because her mother doted on her every whim and seemingly protected her from all the "bad things." SO BASICALLY she's this too bubbly, moderately air-headed, ridiculous human being that's too nice and too trusting for her own good which is how she's a) constantly ending up in trouble, b) a disaster in relationships and should essentially live in a bubble, but instead she's gallivanting around disney as a princess belle performer AND YEAH.
