Horrendously late, but I hope this is worth the effort. In two parts (plus Spoiler Timeline) because it's freaking huge, and very much not dial-up friendly. o.O Screencaps are logo-free, but very dark and roughly trimmed.
I'll probably never do another one this huge again, because this is insane.
Contains profanity. Oh yes. I really mean it.
