Alright, I'll post up my character's thoughts of others then.
@Xytheus
She won't really have too much of an opinion on Grant, however, she will see that he is pretty helpful based on how fit he looked. Though, she would be somewhat worried as well, since she would assume that he would be more rounded on strength rather than speed... That, and he stood out a tad bit. Never the less, she won't treat him any differently from the others.
@Unyielding
She finds Vi adorable, and will occasionally treat her like a little sister against the girl's will. Despite the girl's protests, Amethyst may have the temptation to start playing around with the girl's hair, making her look nice and all for her age. Of course, she wasn't far younger than Amethyst herself, but she likes cute things a lot. Although, she will be quick to catch on that Vi may not be fond of Amethyst at first, and will be cautious as though not to provoke the girl, no matter what reason she may have.
@Inevyr
Yes, she will also think that Neon is a female. Though, she is quick to get into the habit of remembering that he is a male. She may be a little protective of him from others, who may possibly bully him or tease him for looking like a female. Amethyst herself can't help but to want to play with his hair (Like she does with most females) and put it up or something, like a ponytail. She was thinking that maybe she can help him appear more like a male, even if his physique is identical to that of a female, minus the obvious parts.
