When the door to the captains room opens there should have been a gust of wind as the air in the hallway rushed to fill the room which had been emptied of air.
If Trust Industries was taken over by Maddox, then how would Trust know the the abort code on the Maddox retrofit. When a company acquisition occurs, the acquiring company takes control of the acquired company assets and discretion over its personnel and the privileges they exercise. It usually means these privileges are restricted or outright terminated, especially access to the assets of the acquiring company.
When walking down the hallway of the Ark, Brice is obviously much taller than Eva (6'2" vs. 5'6"), yet later they're almost on the same level standing next to each other (so they can look at each other and build sexual tension).
The Ark 1 and Ark 3 are shown perpendicular to each other, and Ark 1 is going ahead with high speed, whatever that is but was more than 3.8 times their earlier speed, and Ark 3 also cannot just be stand still in the middle of nowhere. So, Ark 1 should have reached Ark 3 in no time, or by that time Ark 3 should have gone away from Ark 1's path. But, for a long time, both the Ark were shown at the same space location, as if both have been standing still.
Sasha gets locked in the captain's cabin on Ark 3, and the air vents, so much that he almost faces death by asphyxiation. From outside, Eva breaks the lock and door of captain's cabin opens and Sasha falls out of the door unconscious. If the air inside the cabin had totally vented out, when the door is opened, the air from the bay, where Eva and Brice are standing would also have vented out, making all three of them heaving for air. But it seemed that air from the bay filled the captain's cabin also and Eva and Brice could walk in without life support helmets. Why did venting stop once the cabin's air was totally gone, and why didn't venting restart when the door opened, and if not, why wasn't there a noticeable drop in air pressure because the limited air of the bay now spread to occupy cabin also, nor was there any sign of bay air hissing into the vacuum of cabin in gushes.
