Chapter 22 - "Our Doubts Are Traitors" - Part 1

[nikvoodoo]

I dont know how far away or how many floors away the armory is from the guard room but i would say that odds are(like the number of rooms and floors say that chances are they arent on the same floor) If they are then you argument holds water but if they arent then how fast could you get from one floor to another, in the episode it happens in a matter of seconds. Thats not really possible unless they were like three rooms apart.

When Angel opens the door to investigate, the alarm gets louder so that's why I think they're on the same floor and just down the hall. It's the same setup they had in the first incarnation of the guard room. The store/armory/guard room were all on the same floor just down the hall from each other.

Haven't they said Hope isn't totally 100% blind? She may know more than we originally think about the shooter

Correct, she's not totally blind. She can see "almost nothing but enough to help" (19-1 ~3:00) t I think the best she can see is blurs.

Don't want to get picky, but visually impaired people can't hear any better than sighted people.

Think about it, no-one thinks that deaf people get great eyesight, do they?

People who lose one of their senses can compensate for the loss by heightening their other senses. In this case, going blind can (but not necessarily does) increase ones hearing. Scientifically speaking, Hope's hearing would not be as precise as a child who was born blind. But that's not to say she didn't develop a stronger sense of hearing since she's been put back into the hunter/prey situation of a zombie apocalypse.
