Everyone seems to think that Nerissa = Faith because of similar dialogue and mannerisms. I thought so too until Bigby was shown the photos in the factory. BOTH Nerissa and Faith were pictured in two photos. Wouldn't that mean that some else would have to be glamoured as one of them for the theory to stand true? As a result, I feel like Nerissa is simply a coincidence. If she were Faith this whole time... the whole story kinda shifts and make me see it from a new perspective.
