Hope Kikyou and the rest have caught up to Grey Rose, then our little crew has a chance.
But here is the thing... considering how the vampire society treated the people in the dustbox... Grey Rose is kinda the hero here.
I mean, sure... our little crew are our sweethearts and we know they are good kids, but Grey Rose may as well be the last barrier between the dustbox people and a fate far worse than death, so her zealousness in trying to protect them is kinda warranted.
I know we can say "She should know there are people trying to abolish this outdated system, she should listen and see they are different", but... if you were in her place, with the life she must have lived, with the particular people she has to deal... can you really say you would do differently? I don't have in me to believe I would do better, I hope I would be able to, but looking a little at her perspective, I simply don't find it in me to completely admonish her.
