Her name is Rue, I believe I mentioned it in the first chapter, but I could be wrong.

And for the most part, she has no relationship with any of the characters, Mia and Rue had met only days before the train incident had taken place, but have found themselves befriending each other. I will further explain the relationship between Vince and Rue, within the next 2 chapters, which will make everything easier to understand. But as far as Vince getting upset, I went about it as he thought Rue had put Mia in danger, which left Rue feeling angry and slightly betrayed that he would even think that she would put Mia in that position. He got pissed at her because his family is everything, and he'd do anything to keep them out of harms away. Does that make sense?

And Dom is wary of her because he just met her. He doesn't know what to think of her, and just like Vince, is highly protective of his family.
