Apologies.... I'm only caught up to page 257...
Random but possibly long-term in-play thoughts:
1. That message from the past and I can't recall the link... "one small step, leap, tragedy follows"... thing... Sol... Earth's moon. Going to come into this?
2. New Thargoid wrecks... The space whale thing boggles the mind atm. BUT, what if the little scavengers are actually harvesting AND repairing the main body? As in our knowledge of many creatures on Earth that can loose an appendage and regrow it. What if these bio-mechanical entities can willingly remove parts of themselves to escape? I propose that the scavengers are taking parts of the 'wreck' and using them to heal the main body in a way to allow it to launch or become active again. We are seeing various stages of this process at each site. Think humans and 'skin grafting'.
3. I always thought the prior alien ship wrecks were 'alive'. The scans, the sounds, I never thought they came solely from the UA's strewn about the ground. Those entities are alive and talking. The sounds are all similar to barnacles, which I contend are not human-placed, exploited, yes but not of our making.
4. The colors of all these aliens entities AND the Guardians are of the blue/green hues. They are one and the same in origin, whether bio-engineered or not by the Guardians. The green gaseous exhaust.... BUT what of the yellow from the flower ships? I will contend these flower ships are the OTHER faction.
5. The spectrograph..... I propose that the orbs with grid lines are the SAME body. The probes originated from that point and it is shown at the other end of the image as the return of the data.... not from A to B but from A and back to A.
Mind running off at a fast pace, sorry if I've repeated other's proposals.
Seriously peeved I have to go to a real job in the US and not be at home in the UK like some of you lucky fools. Onward!
