re: What was Arya looking at just before the end of the episode?

The woman and child that foolishly followed arya ... “come outside with this dragon and these murderous soldiers...you’ll die in this private and safe closet if you stay here”

All of the buildings were exploding from the dragon fire and collapsing in on each other. I think it was supposed to be kinda like a trailer in a tornado; it's better to be outside. But you're right that it was totally fricked up they followed her and paid for it.
