The situation on Mars was constantly elevating Sam's depression. He was sent there to devastate Aliens' plan. But after reaching there, he had to know the other threatening plan. But he patiently listened to the male and female whole discussion to explore the truth.
Female Alien: No, it's not like that. If we send all organisms directly to the Earth, the whole solar system can be affected due to the Earth's extinction. We wanna extinct humans, not a beautiful homeland like Earth.
Male Alien: Oh! So, how will we use those organisms?
Female Alien: It's a thing for which the King is waiting. He can't decide how to make
humans victims of those organisms.
Male Alien: Oh, you have all updates due to being so close to the King.
Sam thought that he should keep an eye on the female Alien to be updated about plans.
