"What the hell do you want me to do huh!?" Ryu turned on his heels, scowling at you, his face twisting in anger:
"You want me to apologize for trying to survive!? YOUR PEOPLE PUT US ON THIS GOD FORSAKEN PLANET AND LEFT US TO DIE! And when we refused, they send death squads to finish the job!
Using the teleportation pillars is the ONLY way we can escape this place, and if we don't, EVERYONE HERE WILL DIE! YOU, ME, MY MOTHER, EVERYONE!!!" He was beside himself, it felt like he had this boiling down inside him for too long, suppressed under an emotionless mask and it just started spilling out:
"What the hell do you want me to do?! Cancel the Migration and condemn everyone on this planet to death?!" He was scowling at you so hard, he was beginning to look outright feral:
"The people from your world forced us into this situation, and I will not apologize for trying to survive! YOU LEFT US NO CHOICE!...
Zoy was right. These negotiations are pointless. I'm done with you!" He angrily waved his hand in your direction:
"...I'm going back to Rakshata. The reason there's parasites on Earth is because they could have found a way to destroy our suppression Obelisks, a way to get inside Castle Towns. I have to warn the other Witchers.
You do what you want, but I'm done trying to reason with you. If it wasn't clear, we don't want parasites on Earth either, as it will end the human race, for good this time. So we will be doing everything in our power, to ensure the Castle Towns are secure."
He slowly turned, from the corner of his eye, still looking at you, his eyes burning with hatred:
"...and if you don't extradite the Chariot organization and the Admiral, into our custody, there will be consequences.
I really don't care what you do with this information now. Inform your leaders, turn the world upside looking for them, do somersaults in the air until you find them, or just sit back and do nothing. I don't care.
But if these people will go unjudged and unpunished... there will be consequences.
Goodbye" he turned on his heels and began walking away.
