Samurai X Season 1 Episode 10

Kanryu Takeda: I don't get it. What's his reason for doing this? What in God's name is Battousai the Manslayer doing here? What benefit could there be? What does he have to gain by helping this woman?
Hannya: If Himura the Battousai acted only what was beneficial to him, he would be a high ranking officer of the army at this time. Of course, people like you would never understand.

Hannya: You're the one that needs to understand, Kanryu. Our leader is the only one who leads the Oniwaban group. I don't remember swearing allegiance to the likes of you.
Kanryu Takeda: How dare you!
Hannya: The only one who can give us orders is our leader, Aoshi Shinomori. And we are always willing to die without hesitation for our leader.

Sanosuke Sagara: Hey do you recognize that stance?
Yahiko Myojin: Well, kinda. It sorta looks like the Sei-gan stance, I think.
Kaoru Kamiya: It isn't. It's the Shin-ken stance. The Sword that Believes, it's an old but solid defensive swordsmanship technique that allows you to react quickly to any changes in the opponent.

Kenshin Himura: I see. You have a perfect defense with your kodachi. And your fighting technique is to attack with the same style as Hannya.
Aoshi Shinomori: There's one mistake in your analysis. He uses the same style that I do because I taught it to him.
Kenshin Himura: What? (Feels the effects from the Kempu attack)
Aoshi Shinomori: Master and apprentice are completely different. And if you think we're the same, then you'll end up like that.

Kenshin Himura: A man of this much power. What is he doing this for?
