And given that Quaithe is plainly talking to Dany, then I'm still confused about your interpretation of the prophecy. Given your belief that the "pale mare" can only be Dany, then what does "soon comes" mean? In what sense is Dany about to come to herself?
Soon comes means that someone is coming in Meeren soon. It's 3rd person (comes), so she speaking about someone who is not there.
Second, Dany does not need to come herself, she needs to come in Meeren (hence pale mare who is coming) where all other people will come (to her).
About monologue, we should ask someone who was there, when GRRM read chapter. You quote part of text which is not written by Martin.
I am still thinking that Crow is TEC. The Crow with Three Eyes who comes to Bran. Victorian on Crow's Eye behalf seems likely, but text does not say otherwise. Maybe TEC will come Dany in sleep, as to Bran.
