Interesting. I like the idea of a 'what if' for if Dawn had actually jumped instead. I'd always wondered about possibilities. Anyway, there are some spelling errors. Portal was misspelled, that was the biggest thing that caught my attention.
Other than that I'm going to read ahead, very excited to see what you have in store!

"It needs the blood." Implies that it would have killed Dawn had she jumped, to me at least. I just made the oracles intervene. It wouldn't have been as interesting if she just died.
