Aaaand fail Mira for not actually saying what that massive post boils down to.
Pretty much I don't find sally all that suspicious. She's getting upset when people try to suspect her and I'm still not quite sure where her suspicion of Wilwa is coming from (although in all fairness, I very well might have missed it in the rush to get this done before DL), but nothing about that screams SoE to me.
Now I really want to know Wilwa, Shasta, and phantom's roles are just to see if I'm going to get proven wrong.
