I mean this is a direct result of privatising this particular field, granted.
Though even then, this is something that should have been flat-out mandated when the contracts where going out: "You'll be compatible with one another, and don't even dare start a sentence bitching about it or this contract is immediately torn up".
But damn... this must be so weird for the two astronauts. Second time something on this scale has happened, no? Where someone was uncertainly "stranded" in space? After the stuff with the blown oxygen tank on one of the Apollo missions?
