Master Cheif to a struggling Arbiter in the Graveminds chamber:
MC: "Relax, I'd rather not piss this thing off"
...
GraveMind: *grunt* "This one is Machine and Nerve, and has his mind concluded...This one is but flesh and faith and is the more deluded."
Arbiter: "Kill me or release me Parasite, But do not waste my time with talk."
GraveMind: "There is much Talk, and i have listened, through rock and metal and time, now i shall talk, and you shall listen"
Well, basically this whole Cutscene: Halo 2 GraveMind Cutscene
