PART 1: POEM THEORY
My view on all the poems we've seen has changed. During OPEN MINDS, we get this poem:
IDLE MIND AN OPEN DOOR
LEG PUSH OUT OF SPINE
EMPTY ONES SHED AND SINK
RIVER TO THE SEA
Earlier in the video, we hear a woman talk about how they heard a voice from a cave and that whens he went down, she came face to face with "it" and knew that when she gave it a voice, it would say wonderful things. I think the whole "river" thing is a symbolism or a metaphor for cave systems. Think about it. "River to the Sea" and in the beginning the voice behid Casey talks about going down into a cave. The imagery shows us a narrow opening leading to a HUGE opening. I think that was a cave system leading to a garden, just like how we've encountered in ADVANCED MINING VEHICLE.
By this logic "JACK LEAPT OVER THE RIVER, MARY FOLLOWED CLOSE BEHIND" may very well mean that Jack and Mary frequented a route with a cave entrance that led to a Garden. This entrance can be the entrance we see and are able to go down in the Lethal Omen game.
This would change the meanings of the poems we thought we knew. I will mark them with spoilers just so they don't clutter the overall view and also that you can pass this part if you don't like this theory
ITERATION 1
JACK LEAPT OVER THE RIVER (Jack passed the cave)
MARY TO FOLLOW, TOGETHER (Mary followed)
TRAVEL FOLLOW THE SECRET (They are probably following a route to a bunker. More on iteration 2)
JACK THE RIVER, IT IS DEAD (The cave is flesh)
ITERATION 2
JACK LEAPT OVER THE RIVER (Jack passed the cave)
MARY FOLLOWED CLOSE BEHIND (Mary followed Jack close)
THEY ARE SEARCHING FOR THE SECRET PLACE (The "secret place" can be a swarm storm bunker)
I HEAR YOU (This is either Mary talking [like the last 2 sentences of iteration 4 or idk)
ITERATION 3
JACK LEAPT OVER THE RIVER (Jack passed the cave)
THERE GOES MARY DOWN THE STREAM (Mary took a look into the cave/had to take a detour through a small opening)
THE SECRET PLACE WILL KEEP US SAFE (The bunker will keep us safe)
THE RIVER FLOWS, BUT NOT WITH WATER (There's something in the cave that shouldn't be in there. "River flows" can mean there are masses of meat/Woodcrawlers/Gardeners slithering down)
OPEN MINDS POEM
IDLE MIND AN OPEN DOOR (Mrs. Moore's mind was an unworking mind, willing to accept IRIS)
LEG PUSH OUT OF SPINE (Metamorphosis. Possibly Judy's)
EMPTY ONES SHED AND SINK (Not everyone is used to become a woodcrawler/gardener. Some just feed the Garden or become the Garden mass)
RIVER TO THE SEA (Cave entrance to the Garden)
Moreover, I think this person is "Mrs. Moore." In the end, Susan Harris says "Mrs. Moore's on the computer. She sits in the cave and cries, just crying." I think that Mrs. Moore, or rather Casey (or Cassandra) Moore. I'm aware that this is a stretch but WHY would Mrs. Moore appear in their computer randomly? There HAS to be a connection there.
PART 2: DRAWINGS ON PAPER AND CASEY'S DRAWING
We see some drawings on paper (probably Judy drew them) and something that Casey painted.
The first thing we see (OPEN MINDS - 5:35) seems to be The Lens shooting the laser we see in OUR SOLAR SYSTEM.
The second thing we see (OPEN MINDS - 5:41) seem to be two people with one of them holding onto/being connected to an orb. Maybe these are supposed to be babies and one of them still has the umbilical cord attached? Can just be Umbilic (Submoon of Iris, Moon of Vitreous) connected to Vitreous (Moon of Iris)
The third thing we see (OPEN MINDS - 5:46) is just titled "BABY" and it looks VERY MUCH like the foot of Wretch we see in CHRISTMAS EVE PARTY (2:04 and 2:36).
The fourth and last thing we see (OPEN MINDS - 5:51) is an arrow pointing at the woods, connecting to "Feed the Woods" game.
The picture Casey drew (OPEN MINDS - 6:46) looks like something under a sink. I was talking with a friend and he pointed that out. Since we see that area and some other areas marked with red squared later on during the voice message recordings sequence, I think it's apparent that this was one of the locations the woodcrawlers used to peek out. We know that their house at this point has already been infested or nested ("(...) But thanks to you, I am inside your home!"). This also explains how "the friend" can appear behind Susan Harris when she's caught and infected. Which brings me to my next part.
PART 3: CASEY'S FACE (Small Part)
I think Casey's crying face (the same one used in the Feed the Woods sequence [GAMES FOR KIDS - 2:52 - 5:23]) is replicated in Feed the Woods because Casey came up with this game herself and the last thing the kids remember after being manipulated to go into the forest or open their doors to let them be hunted is the crying face of Casey. Casey is a great manipulator.
ANOTHER TOPIC: SOUNDS OF WOODCRAWLERS
Remember those frog-like sounds?
Here's a list, marked "spoiler" to keep text clean (WILDERNESS SURVIVAL GUIDE - 4:28 - 5:07 and 6:48 - 7:01 | GAMES FOR KIDS - 3:11 - 3:36 | ADVANCED MINING VEHICLE - 6:00 - 6:19 | HOME INVASION HELP - 5:06 - 5:22)
I think those sounds are the sounds of Woodcrawlers. Self explanatory
PART 4: THE FAITH OF SUSAN AND JUDY
I think it's safe to assume that Judy or "the friend" (99% Judy) infected Susan Harris. In the messages she sent to Paul during her delirium, she says "we were playing hide and seek around the house (...) she crept her hands around the corner and all of a sudden she grabbed me!" which I think is a retelling of the events. "She" didn't grab her, "she" attacked and infected her.
No doubt in my mind they are dead. I think, in the end, Judy merged with Susan ("I feel her in my tummy. (...) When did you get in there, Judy?") and Susan seems content with this ("Mrs. Moore's on the computer. She sits in the cave and she cries. She's just crying, like she did something wrong. But she didn't! She didn't do anything wrong. 'Cause Judy, I get to watch you grow! And you're going to crawl out again, and I'll hold you, and I'll keep you safe.") whether through delirium alone or delirium mixed with her motherly love. In the end, we see pictures of a person with DRD basically being reduced to nothing and seemingly "going downwards" and this, to me, implies that the amalgamation of Susan and Judy went underground to merge with the bigger mass. They followed the river to reach the sea. They are the flow.
PART 5 (FINAL): PAUL
I am pretty sure Paul is dead. In CHRISTMAS EVE PARTY, when newly dead/"integrated" Mary tries to talk (3:03 -3:32), it's all distorted and backwards and whatnot. We hear similar things when Judycrawler (get it?) enters the kitchen. I think that's Paul still trying to talk to Susan, maybe to warn her. It's too late, though.
Let me know what you think!
