I think if they explore the nature of the dark ones curse, and power, it will have something to do with blue. Perhaps the dagger is a way of containing the power, controlling it to a certain extent, because it is an explosive power. I keep thinking that blue knows something, maybe she knew the first dark one. I keep having this thought, that there is a physical manifestation of the dagger – a person – who was the original dark one, who is forever bound to the dagger, and their power wielded by a desperate soul. Blue’s ex? Haha. This is of course total conjecture, and my imagination running away with me.
I am just really excited to find out more! I’m convinced that Blue knows something, and it’s huge.
