Small correction about the Kuragin mission, they didn't burn up on Titan but skipped off its atmosphere and they will crash on Saturn ( or be killed by the radiation as Kelly says), which to me is even more brutal because the Kosmos crew will see this coming knowing they have no way to prevent that. That was one hell of a way to start the episode.
I have not much to add to your post though as you routinely express about the same feelings i have to the episodes and it's getting annoying
I didn't have a Mars colony split on my bingo card though, i thought this episode would see the handling/resolving of the two camps on Mars but it seems there was a kind of stalemate as neither side was willing a full on battle yet. One thing did come to pass was that ISN nations supplied them for a while but have now pulled out because it led to a possible confrontation with M6 nations on Earth and they were not willing to go to war over Mars. Fair enough but even without the dome breach i don't see how Miles, the de facto Mars leader, can win strategically.
Marines are surely on their way by now even if the show didn't mention them as the focus was elsewhere but given all this episode revealed now the Martians are with their backs against the wall with no support from anyone and an incoming military force plus Dev's hostile group.
The Titan mission served to unite the Martians for a while, to give them a sense of accomplishment and identity but the fact remains they have food left for 2 weeks, possibly being extended by hard rationing to maybe 4-6 weeks ( and that means slightly above starvation) which creates an impossible situation for Mars.
