Nari & Vi
When the symbol went up, Violet felt a bad feeling in the pit of the stomach return. That symbol meant a lot of bad things. Especially bad things for Muggleborns like herself. She knew enough of Lady Nyx and her followers to know that. The school was supposed to be this safe place. A place where a symbol like that couldn't make it onto school grounds. School was hell in a lot of ways, but the really bad things were kept out. Only the bad that people had brought in their hearts were what came into the walls of Hogwarts.
Her own fears were immediately shoved away as she saw a reaction from the corner of her eye. Nari. The blond girl always wore her emotions on hear face. You didn't have to ask what Nari felt because one look and you knew everything. And Violet could tell that the symbol affected Nari in a lot of ways. So she ended their current estrangement of sorts (since Vi had put more distance between them since the Hufflepuff party) and drew closer to the girl with the big heart. Immediately Violet took the girl by the hand and started to lead her away.
It was a miracle they got to the Hufflepuff commons but they did. Violet had refused to let go of the other girl's hand and was determined to get them to wherever safety could be found. The announcement told them the commons, and so that's where Violet led them to.
Once inside, Violet didn't let go of Nari's hand, almost as if she were afraid that if she let go Nari might disappear.
