I wonder if anyone has thought of the implications of an alien invasion.
Yea. You don't invade planets without having a plan. That's why they're called planets, to remind you to plan it.
But more, our side. You don't send your entire planet to invade someone, which means this is just the occupation force. We are going to have to invade them in response or they will just send another army.
One suave guy threw a knife at an alien and other stuff happened, but Elis was more interested in her bundle of scrap. It was going to work, she just had to make it look better for those who judged it solely on how it looked.
