Alright, here we go.
Pity is the last thing Ophelia wants for she is trying to stand alone against her past and things that have hurt her, so if anyone would pat her on her shoulder, and that only because of her blood status, she would be offended and she'd misunderstand Calixta completely because this whole thing about blood-this-and-that is yet too strange for her. Maybe, if Calixta would recognize her potential and smarts, they would get along, but otherwise Ophelia would avoid her like anyone else.
Ophelia gets confused with first year students due to her short height. She is 154 cms "long" and with huge glasses that make her eyes seem even bigger than they already are, she may appear like someone who is still growing up, so idk, maybe Malaika can confuse her with another first year student as well, and Ophelia would just go along with her if the girl is nice enough with her. She is quite a bit afraid of strangers still.
As for the Ravenclaw prefect, I think Ophie would use the opportunity and always run to her should anything bad happen. Like, hide behind her and cry and complain about this and that, but not that much though, as she is afraid of revealing too much.
And she would stay away from Ariane Catchpenny since well... she has had enough of rumors circulating either about her or other innocent people.
I think that, for some reason, if she and Selwyn would get into talking, they would get along well and she would grow to respect him.
And with the rough past like Destrey, I think so too that they would understand each other quite well.
So... in the end, I don't mind roleplaying with Malaika, Jenna, Selwyn and Destrey, and of course with the others as well, I just can't imagine how they would suit with Ophelia.
I am sorry about that.
