That last episode. Noooooooooooooooooooooooooo ;_;
I understand WHY they did it, because at the end of it all Orga was just as much of an awful person as anyone. Once they did their duty at the end of Season 1, they could've just ended it there and not got involved in any more wars, but then due to his own greed he put his own guys in danger countless times.
HIs final act and his redeeming act was rather than suicide charging which has basically been their motto this entire time he found an out for everyone. He found a way to try and get everyone away from all this shit safely and give them a place to "be". Still hurts like hell though, despite his shortcomings Orga was awesome.
It wouldn't surprise me if this was McGillis' men, because he was the only person really to know that they'd be going there. I hope Mika slices him in two.
