Ok since they are both dead no reason not to tell about them. Devyn was the true seer, SnS had a protective role and had been protecting devyn. I am Melisandre and I could also investigate with my shadows and I cleared devyn and SnS at the beginning of the game. I have run out of shadows. SnS couldn't kill devyn since multiple people knew she was suppose to be protecting her. it is fishy that the second SnS dies the seer is immediately taken out. Only myself, LIS, and DocE know that devyn was the seer and possibly packen.
