I suspect there are interlinking bits that only make sense after we've seen all 18 parts....planning a re-watch of the 18 hour film....wait, is that a puzzle piece on the floor under the coffee table?
Every line and every scene must be invastigated very carefully, as the sound...there must be some critical points...like when Chantal went for hunt, before bullets, two tulpas just disappeared! i think there are too many missing pieces all around the scenes, decoration etc..
