"Once the shield is down, we will head straight to the Library. I do not wish to keep the Hierarchs waiting." - To the Arbiter, when flying to Installation 05's Library on board a Covenant Phantom.
"Who do you think?" - In response to the Arbiter's question on who the human was that killed the Prophet of Regret.
"Hmph. Why, looking for a little payback?" - To the Arbiter, who is surprised that the Master Chief is on Installation 05.
"Ha ha ha ha, of course." - To the Arbiter, who claims that his only concern is to retrieve the Sacred Icon.
"Lower the shield Arbiter! I'll pick you up when you've finished!" - After saving the Arbiter from a ForerunnerEnforcer.
"You're getting close to one of the Shield Generators, many of my Brutes have fallen attempting to take it down. Lets see if you fare better." - To the Arbiter, who draw closers to the Containment Shield's generator.
"You've reached the power source, Arbiter. Overload the locks holding it in place. It is useless to attack an Enforcer from the front, especially when its shields are up. Stay in the shadows, wait until it loses interest, then strike the beast when its back is turned." - To the Arbiter, who encounters an Enforcer guarding the generator.
"Release the power source. Now, find a way to remove it from its cradle." - To the Arbiter, who eliminates the Enforcer and disables the locks.
"Our path to the Library's clear. I'll pick you up on the ledge ahead." - To the Arbiter, who disables the shield.
"Blasted machines! Make your own way through the wall, Arbiter!" - When flying the Phantom to the Sentinel Wall, but attacked by more an Enforcer and group of Sentinels.
"I see that coward didn't join you. I'll do what I can to keep the Flood off your back." - To the Arbiter after Rtas 'Vadum leaves to fight the Flood.
"We cannot let the humans capture the Icon. The Hierarchs do not look kindly on failure." - When the Gondola Arbiter is on starts moving.
"I'll thin their ranks." - In an attempt to lessen the Flood's numbers.
"Humans, I'll deal with them." - When he spots the Human forces on the other Gondola.
"The humans are already inside, Arbiter! After them! I'll watch the perimeter." - When the Covenant troops' Gondola has reached the Library.
"Hurry, Arbiter! Get the Icon!" - To the Arbiter, rushing him to get to the Icon before the Humans.
"Was your responsibility. Now it is mine." To the Arbiter stating that he is taking over responsibility of the Icon.
"A bloody fate awaits you and the rest of your incompetent race, and I, Tartarus, Chieftain of the Brutes will send you to it!" - To the Arbiter as he betrays the Elites.
"When they learn? Ha ha. Fool! They ordered me to do it!" - Talking about the Prophets cooperating in the betrayal of the Elites. Moments before attempting to kill the Arbiter, who is subsequently rescued by the Gravemind.
"The Demon has infiltrated the Council Chamber! Protect the Hierarchs! Seal the exits!" - Through loudspeakers located in multiple areas in High Charity, when the Master Chief teleports into High Charity.
"Reinforce all approaches to the holding pens, slay the Demon on sight!" - Through loudspeakers, to the guards in High Charity.
"Rise, pack brothers! Cast down the Elites!" - To his fellow Brutes through loudspeakers, marking the beginning of the Covenant Civil War.
"Once the towers are clear, we'll drive them from the lower district!" - Commanding the Brutes on the loudspeakers.
"The Elites are falling back to the Mausoleum. Fools! Their Arbiter can do nothing for them now." - Through loudspeakers, mocking the leader-less Elites.
"My faith is strong. I will not fail." - To the Prophet of Truth, who hands him Halo's Activation Index.
