Mel's POV chapter has her remembering being sold at a slave auction, and TV Mel said as such to Gendry. I really, really really don't see her as Shiera Seastar. Not every old witch is SS.
Some stray observations: The exchange between Ser Davos and Ser Alliser brought some much needed humor to this episode. "And some mutton". (I think Ser Alliser meant it when he promised safe passage and amnesty, I still think of him as having a rigid system of honor.)
Anyone else notice how much Olly has grown up since FTWing Jon?
