	Generic
	Generic	You're a curious one. Most wouldn't risk the stigma that comes from working with an assassin.Actual line: You're an odd one. Most wouldn't risk the stigma of working with an assassin.
	Generic
Partner with Jin Kisaragi	Jin: Ally or enemy, I've never liked how cowards like you fight. If you want to be a shadow, then crawl along the ground where you belong. Seth: Your military approach to combat has blinded you. A shadow does not creep along the ground. It casts a wide shroud upon the world, invading and overtaking all in its path.
	Partner with Jin Kisaragi
Partner with Hazama	Hazama: An assassin taking the leading role in a farce? You really are a disgrace. Seth: I could say the same for you. No matter how we struggle within the confines of our role, we're both destined to fade into darkness.
	Partner with Hazama
Partner with Izayoi	Izayoi: You are an arbiter of sin and punishment, assassin. Yet you still refuse to step into the light of justice. Seth: Behind every light is a shadow, and that is where the assassins dwell. You and I achieve the same goals, but I expect no glory. Such is my role.
	Partner with Izayoi
Partner with Es	Es: Speed, strength, precision, training... All are represented in your assassination technique. How praiseworthy. Seth: Don't say that so lightly. It makes you sound sarcastic.
	Partner with Es
Partner with Yosuke Hanamura	Yosuke: Is it just me, or do we kick ass together!? The speed, the knives... It's like we're meant to be together! We're like...the Badass Brothers! Seth: (I need to lose him, the first chance I get...)
	Partner with osuke Hanamura
Partner with Teddie	Teddie: Oh come on, turn that frown upside down. When you win, you gotta smile! Seth: Silence. I don't play nice with clowns.
	Partner with Teddie
Partner with Naoto Shirogane	Naoto: That worked out remarkably well. Between your logic and your technique, I believe our partnership will be a fruitful one. Seth: How arrogant... to assume you can keep the Night on a leash.
	Partner with Naoto Shirogane
Partner with Mitsuru Kirijo	Seth: Forgive me for my impropriety. My skills must have seemed brash, in the eyes of a lady of your standing. Mitsuru: Not at all. What matters isn't one's status, but their resolve.
	Partner with Mitsuru Kirijo
Partner with Hyde	Seth: Unrefined, sluggish, and worst of all, naive. You really think you're worthy of carrying the Insulator-- the Night Blade's masterpiece? Hyde: I do. I can carry anything the Night Blade throws at me. Including Linne's wish.
	Partner with Hyde
Partner with Linne	Seth: Don't forget, Traitor Princess... I won't let anyone else absolve you of your sins. Your punishment will be at my hands. Linne: You can try. My corruption is too great a burden for a child like you to bear.
	Partner with Linne
Partner with Waldstein	Seth: You still wander the path of heresy, Hecatoncheir. One day I'll bring those wanderings to a perfect end. Waldstein: One day, you might. But now's not the time to ponder my fate. If you consider yourself a soldier, you should be indulging in the joy of battle.
	Partner with Waldstein
Partner with Gordeau	Gordeau: Damn, man, you gotta lighten up. Have some fun! We don't get to fight people like this every day. Seth: That's not happening. I'm an assassin. I don't revel in my work.
	Partner with Gordeau
Partner with Blake Belladonna	Seth: The agility of a beast, the mastery of a human... I see now. Your distorted existence gives you your fangs. Blake: I define my existence, not the other way around. You don't know the first thing about me.
	Partner with Blake Belladonna
Partner with Yumi	Yumi: You fight evil with evil... Where is the justice in that? Your existence must be a fragile one. A long walk on thin ice. Seth: Your concern is misplaced. A shadow draws no distinctions between good and evil.
	Partner with Yumi
