Finally finished my rewatch of Iron Lung and I'm GNAWING.
The theory I had about when each O2 ligh goes out was a bust, but oh well. ON THE OTHER HAND, the fact that VLC allows me to increase volume is making me INSANE at the end. Too many notes to help me with other analysis, but this one thing I need to talk NOW and please @water-activated-light and @trinikins come hear!
2:00:06: this is the EXACT MOMENT the seedling's roots burst from the pendant. Before, any and all growth seen is from the blood and is activelly growing over it , as seen in these ones
1:57:00 (this one actually looks very much as it was in the Blood Dimension)
1:59:25 the blood vein is even THICK, almost looks as if trying to breach the Seedling/Glass?
01:59:46, just after the Eel says "pray that you stay dead!", we have "We are salvation!", VERY CLEARLY by the Eel, but the line "We are hope", bursting VLC out of bounds... "We are hope" is whispered in a way that it wasn't before by any of the SM-8 researchers; in a way, it almost sounds very young. The voice sounds very soft and uncertain, and neither SM-8 people heard spoke this way. ALSO, the SM-8 Lead and Assistant speaks always about Salvation; when meeting the Light, the Eel specifically says "This is our salvation. Our promise". It also speaks "we are one in the blood" once in the Blood Dimension. The SM-8 people NEVER speak about hope.
We have TWO CHARACTERS speak "hope" with all the letters: David, and the brother that left the Seedling pendant: "This is the only hope I can offer." "If there's still hope, it lies beyond the veil. Hope in this void is as illusionary as the starlight."
"This is the only hope I can offer", meaning, the Seedling pendant, because this Brother from Eden managed to hide his, when we learn later that COI takes the Seedlings to create its own garden.
"We are hope" is the Seedling speaking. And It is still in Simon's arm and it kept him in place in the Blood Dimension, as if an extension of him (it has no eyes to see and can't leave the blood ocean)
Another thing: just before the roots burst, we have "We are one", very clearly starts saying by the Eel, but the "one", the voice changes, and sounds as the one that spoke "we are hope"; also, the other time we have "we are one", it's the Eel speaking "We are one in the blood". In the blood in not being said.
Finally 02 00 07, the roots going for Simon, his left eye BURSTING into light, and we have, in the same voice-whisper from "We are hope": We die. We live! We!"
I don't think I EVER noticed the Eel speaking about dying. No. About salvation, about knowledge, about freedom, but not this.
But "Dying to live" IS a very typical imagery associated with PLANTS. While not exactly biological, the idea that a Seed needs to Die before it can Grow and Live is very prevalent.
"We are hope" finishign "we are" with only "one" "We die. We live! We!", I think, is very much possible to be the Seedling. If THIS is the moment it gained awareness, or it gained before, I don't know, but this is definitelly the moment that it speaks, and, I would risk, It says "we" and "one" in reference to Simon. The Seedling and Simon are one, are "We", and his eye glowing with what looks like electricity bursting out and reaching the roots may very well the moment they Trully became One.
Finally, the Eel says that "It wants you to do this", and I think this may very well be true, the Pinhole God wanting the black box to reach surface, but I'm absolutely Not Sure that the Pinhole God expected THIS of the Seedling, expected it to grow and become a Tree and take Simon.
Anyway. Yeah, I think we can faintly hear the Seedling by the end and it sound young because yeah, it's a Seedling, young plant that will become a Tree.
