This was very good. Granted, I did have to read it twice, but on the second time through, I felt like I had a pretty good grasp on what was happening. Considering that I'm missing the context, that means you did very well describing the events.
The only thing I would point out is that some of the sentences read a little weird, so maybe go through it and touch some of them up. An example would be the last sentence of the second paragraph. If you do that, I feel this would be a very solid prologue. Other than that, great job! I liked it. :)
Thank you so much :D This story is still a work in progress so that may be why things seem unclear right now. The last sentence in the second paragraph is talking about how his eyes looked dead (talked about in the epilogue from the previous installment), and they were fading back to his original icy blue color, and his gunshot wound had been healed by Valentine. I'll take your advice, though, and edit it right now.
