Remember that Mina’s ordeal is the worst thing going right now: who is reacting to it the worst? Who is bearing up pretty well?
The confrontation at Carfax: victory? defeat? stalemate? You decide!
Originally the group decided not to tell Mina what was going on. This decision led to her ‘baptism’ by Dracula. Now that Dracula can interact with Mina’s mind the group once again excludes her from their deliberations. How are these two exclusions the same? How are they different?
Hypnosis was cutting edge science at the time (as was trepanning, phonographs, etc). How do the protagonists incorporate both new technology and old beliefs in their fight against Dracula?
