Sorry, but this is exactly the type of "I'm biased toward the girls and found the guy repulsive in that situation so i build up a line of reasoning based on wishful thinking that would save them" type of theory [...]
How can we, players who've seen the MC being shoot, find him repulsive... since we are the ones that took the decisions leading to this ? And I saw it, months ago I even complimented Nottravis for this scene that I found really funny. I don't know for you, but personally when I play, I totally avoid the choices that repulse me ; even if I made an exception this night to please Nottravis, and I'll probably be more wise the next time, because I still see this fucking monster wherever I look.
So, sorry for your divination, but it was the "I've lived long enough and learned enough about history, to know how it can happen in real life since the start of History,
and I'll apply this knowledge to my own version of the fan fiction named 'what happen next'", type of comment ; because, how can it be a theory since, like you said yourself, we are talking about a VN ?
So i disagree with this "noone would care" attitude you suggest that would affect the entirety of the fleet, high command and the dude's very own sister, which would be required to absolve the girls because its entirelly wishful thinking nothing else..
Custer's Last Stand, to take only one example, and a recent one, is the undeniable and now not denied, proof that it happen in real life. Marcus Morris was judged innocent because it was in the interest of the Government that the sole responsibility of the massacre stand on the natives, and not on the many failure of the army, and at this time, any voices that goes against this judgment were silenced.
Therefore, there's no reason for this to not happen again if the lack of investigation ensure that the colonization process, apparently vital for the human race if I understood correctly the news on Channel Seven, will be kept safe. I don't care about who shoot the MC and why he was shoot. Whatever these reason, for me the conclusion would be the same, even if he would have been shoot because he just refused to play Chris' game.
If an aspirant pilot can shoot civilians that gone full rampage and still have a career, and
in this story she can, who would be bothered enough by the death of an engineer, where the future of the humankind is possibly in the balance ? Kelly ? Sorry, but no.
She don't know that he's serving on the Intrepide, so one day she'll receive a letter saying that her brother is dead, and if the condition of his death are included, it will be the official version. She'll be sad, obviously, but at this state of the story, she have no reason to suspect anything and ask for more explanation or for an investigation. In fact it's the opposite. Being in Ophion, she experience material random malfunction and failure every single day. So, even if she learn that he was on the Intrepide and died will going to Ophion, she'll not question the explanations. A console malfunction leading to a random fire of a cannon, at the limit of Ophion atmosphere ? Well, every single day the reactor of Ophion goes down and up for no apparent reason, and I don't even talk about the communications malfunctions and failures, what she know better than anyone since she's in charge of them.
There's no apparent mystery here, no reason to be revolted, to ask for more explanations and/or investigations, just the sad truth, her brother is dead, "now please leave me alone, I need time to cry him".
plus this is a VN, if Notty wanna write it like that suddenly tulips would grow on the ship's hull then that would the story's canon.
Absolutely no one here, at least no one talking about this subject, said otherwise. None are discussing Nottravis story, we are sharing our own vision of the unwritten (and it will probably never be wrote) outcome of a particular scene. Its our way to express our interest for the piece of art that is this game, and to trick our eagerness to see the next chapter, nothing more...
