If you watch the video there is an intentional screen ditortion that occurs at the end of the loading screen right before the message pops up, implying this just happened. Also why would they bother putting it in as a chance to happen at the beggining or end of a mission (times when you could have a chance to lose connection to a warframe where it wouldn't affect gameplay) if it was a remnant of the awakening of the tenno and not start the tutorial mission with it?
Here's what I get out of this:
-Void-Link Severed
Your connection to the Warframes is linked via the void and it was interrupted.
-Reason foreign carrier detected. Origin unknown. Suspection trapping signal.
The reason it was interrupted was because another sigal interfered with the connection.
-Reinitiating dipolar connection in novel carrier. Bio in standby for check and sync.
It's attempting restating a connection with a new signal and vitals are on standby to be synced up to.
-Motion compensation complete.
This is either compensation for the Warframe's movement when uncontrolled or the locational diference of the Warframe being connected to since the last connection.
-Selenic lensing locked.
I'm sticking with the moon, maybe that's where the Tenno are kept? perhaps the moon base was the facilty the Tenno were created on and subequently where the controlers are, and there is something there that extends their reach through the void?
-Somatic control established.
Whatever system is involved has taken control of the Warframe's voluntery movements.
-Margulis implantation intact.
I can't 100% about this but given that Margulis is an alternative version of another name and the best known person with that last name was one of the principle scientists who studied cellular endosymbiosis, a theory where multiple individual cells came togeather to evolve into one cell which would lay the foundations of multicellular lifeforms. Not sure how that plays a part, mabe it's metaphorical where the Warframes are individual cells that each have ecome part of our arsenal and as such they are all tethered to our will and are more than just individal and are now part of a larger whole? I feel like I'm reaching on this one.
-EVM status nominal.
So based on the somatic nature of the Tenno language I didn't realize it before but it seems to be an abbreviation, the only one that seems to make sence is Error Vector Magnitude, which is a measure in digital radio signals that compares difference at a given time between the transmitted signal and the received signal which, by the way, plays back at the 'unknown carrier' part of it as the modulated waveforms that carry information in such communication systems are called carriers. (Carrier leakage is what it's called when two such waveforms interact and bleed onto oneanother.)
-War platform awaiting sync.
The Warframe is prepared for us to sync up to it.
-Initializing somatic overlay... Good night, sweet angel.
The control Tenno's desired movements are being overlaid overtop of the Warframe's body and the conciousness of the Warframe body is being suppressed, thus the 'Good night, sweet angel' creepyness.
