I usually find a very clear connection between the title of the episode and it's meaning, yet the meaning of this title eludes me (perhaps because it goes no deeper than the one-way glass in the abduction room). Any thoughts?
Edit (10/26): Today we were talking about where the 'dark and scary' comes from in Carroll's books - the impulses that come from inside us and our subconscious dark desires - and why it's there. This, I felt, addressed my confusion about how Carroll's books related to this dark, twisted death-filled episode. Perhaps that's what this episode is urging us to see - that Carroll's books address the darker side of humanity, subtly, the scary side of humanity that lies under the beautiful innocence that we first see in imagination. Just as the families seem innocent and perfect in the beginning, as the story progresses and the unsub reveals their dark secrets, so too does Carroll reveal the dark side of imagination.
Does this seem to be asking too much from the producers of the show? Am I finding meaning in something that may not have much meaning?
