SM-13's Entry Hatch & Implied Scene
I received a DM from @daniqueeninabox asking: where is the door into the rover?
Well, I'll tell you: There is no door. There was a way in, but not anymore.
From deadlymelodic's concept art, we can see that there is a ladder up onto the top of the submersible to a hatch...
...but in later iterations of this vessel, it's gone, with nothing but the ladder remaining:
They took the hatch off, and what's left is a smooth panel. We can further confirm this by having a look at the interior ceiling, where the hatch would have been:
This implies that Simon was shoved into the rover from above and fell into it.
Into pitch black darkness, with nothing but the sounds of echoing machinery and people from the outside.
We see upon entering the tow ship, that the power is cut for safety reasons. I mean, it's pitch black in there:
The only reason the x-ray camera went off was due to David accidentally wiring it to the back-up battery. Otherwise, the power would have been cut off from that, too.
So, Simon would've been sitting in there with a bright screeching light above his head, probably trying to avoid flying sparks, as he watched them seal his fate.
There's a whole missing scene to be implied here if you think about it. Horrifying.
