Several people have been asking me about the ending to this fic, truthfully when I fit had the dream about it I was just as confused. So there is no one specific answer to what is the ending there are actually four endings all open for interpretation.
1) Will dreamed everything and we are still in the continuum of the tv show.
2)Hannibal and Will are on their way to the refugee camp. Hannibal's antidote worked and he is now going to carve a bloody path through the remainders of society. The scene in Hannibal's office at the end is wishful thinking on Will's part and he is dreaming in the car.
3)Will is dead. The last two scenes (the car and then the office) are just his last thoughts as he dies from the virus.
4) this ending I really never thought about until just recently reading through it. So Will wakes up in Hannibal's office at the moment from the beginning of the fic. The Zombie apocalypse will take place but this time Hannibal, Will and crew do not have the jump on the situation.
So yeah, pic one of the four and that is your ending. Truthfully I like the first and the fourth one...but yeah its all up for interpretation on the readers part of what is real or not. Hope this clarifies some things up for people.
