Holy hell how did I forget that! >.<

Why is no one suggesting Sansa might be writing to the Blackfish? She was almost going to do that a few episodes back but was worried about it being intercepted. I'm guessing she's now willing to take the risk, now that they really need more men. Problem is she doesn't know about the Lannister/Frey siege (I think?).…

Oh hadn't noticed the sound of the staff. That makes more sense.

Did anyone else notice the waif's expression when Arya says "Walder Frey"? She stops and tilts her head and seems to find it interesting, or maybe taken aback. And I felt it was meaningful in some way. Maybe she was a Frey daughter in the past or something like that. Anyone else catch that moment and interpret it that…
