I'm not going to say who I think the seer is, but if I'm right, Saucy was dreamt on Night One. (darn it) On Night Two I was dreamt and found to be innocent. Guy was dreamt Night Three and found to be innocent. I'm really getting more certain of this the more I read, based on context. Mormegil was dreamt on Night Four, and found to be innocent.

I am not going to out who I believe to be the seer.

Add to the above Cailin's claims as the assumed Changeling, that Mormegil, Guy & Durelin are innocent, and that she doesn't know about, but suspects me.

Based on this theory:

known innocents
Caranlondien
Durelin
Guy
Mormegil
