Around the time of Stannis marching south towards Winterfell, Melisandre mentioned various things that she'd forseen in the flames, which she took as proof that they'd win. I think she also mentioned similar visions to Jon and possibly also to Davos. As usual, she had subtly misinterpreted them.
I don't remember what these were and I'm struggling to find them in transcripts etc because I don't remember which episode(s) they were in.
All I remember is, she saw someone (Jon?) walking on the ramparts of Winterfell, and there was something about Bolton banners being cut down. I think there was also something about things burning (not sure how you see flames in flames, but nevermind!).
In the latest episode (S06 E09) we see:
A shot of Melisandre watching a Bolton banner be cut down and replaced with a recently-sown Stark one - clearly a nod to her previous vision
What were the things Melisandre saw related to Winterfell? Bonus points for how they relate to what we've seen so far.
