When you ask the mirror about Faith, he answers:
Through powerful magic her whereabouts concealed, unfortunately for you, "these lips are sealed".
Also, I've noticed that if you go to Lawrence's place instead of Toad's first, you'll have to inform him the news. If you choose to say Faith is dead, it will show "You told Lawrence that Faith is dead", not "You told Lawrence the truth".
My question is, is there any chance that Faith's death was fake?
What do you all think?
