"It seems you still haven’t figured it out. So, I’ll spell it out for you. Get it? This is war. Do you still expect mankind to just accept those who wield such power as we do? That’s completely out of the question! They’d come as a bloodthirsty mob to bind us and kill us! The way they’d treat those who threaten their security… by now, it should be engraved on your very soul!!"

"If it comes to that… let’s run away as fast as we can. And then, when things have settled down a bit… we’ll quietly approach them again."

"It’s taken you over a century and that is what you have learned?!"

"I want to forget what happened yesterday. But you know I can’t. I can’t do anything about my regrets. But for now, my hands still work. It’s only when I’ve eased someone else’s sorrow that it becomes a little easier to bear. Tomorrow… and the day after tomorrow. That’s why, no matter what happens, I won’t let you have your way… Knives!!"

Here you go, Knives and Vash from Trigun. Brothers trying to convince the other that he is wrong. Knives trying to convince Vash that the human race is hopeless and that the only logical course of action is to eliminate them. Vash trying to convince Knives that the human race is worth saving, and that he will do anything he can to save them, even if he dies in the process.

You may notice the large amount of black hair. Lots on Vash, little on Knives. This is because, later on in the manga, both brothers' hair begins to turn back for reasons that I will not tell you (must go read the manga yourselves ) Also you may notice that feathers are growing out of Vash's face…… another thing I will not explain to you.

If they ever make a real-life movie out of Trigun, they should use Alexander Ludwig for Vash and Knives (when he gets a little older that is). He has the perfect face for it in my opinion.

Anyway, full view please do not steal

and enjoy.
