"How could we have become so different? Why can we no longer understand each other? What did we do wrong? [after finding out that the heretics have been spying on the other Geth, whereas normally Geth freely share data]"

"If we do not rewrite them, we destroy them. Do not hesitate now. They will exterminate your species because their gods tell them to. You cannot negotiate with them. They do not share your pity, remorse, or fear."

"Windows are structural weaknesses, Geth do not use them. Approach the hull at these coordinates."

""Home" is recognized patterns. Known spaces. Familiar thought processes of fellow sapients. It is belonging. A planet is an amount of material massive enough to collapse into a spherical volume. Rocks, ice, and gasses are not "home." The home of the creators is where the creators are. Their place of origin is not relevant—-only where they choose to go together."

"Does this unit have a soul?"

"I always work at optimal capacity."

"I have control."

"I enjoy the sight of humans on their knees ...That is a joke."

"[When a mineral probe is launched onto the planet Uranus] Really, Commander? [When a second probe is launched] [sigh] Probing Uranus ..."

"I am the Normandy. [Joker] is a skilled helmsman. I trust him to keep me operational, he trusts me to keep him alive."

"Cerberus regulations are clear, Mr. Moreau. [almost annoyed] Personalization does not include grease on my bridge cameras."

"You walk within my... body. Tickling me with your footsteps. That is a joke."

"You will all be my slaves."

"ASSUMING DIRECT CONTROL!"

"We are the harbinger of their perfection. Prepare these humans for ascension. [orders given to Collectors on Horizon after subduing all the colonists]"

"I will show you true power."

"I know this hurts you."

"I know you feel this."

"If I must tear you apart, Shepard, I will."

"Your worlds will become our laboratories."

"[to Shepard, as the Collector base is about to be destroyed] Human, you've changed nothing. Your species has the attention of those infinitely your greater. That which you know as Reapers are your salvation through destruction."

"[to the Collector General immediately after] You have failed. We will find another way. Releasing control!"

"Shepard. You have become an annoyance."

"You fight against inevitability, dust struggling against cosmic winds. This seems a victory to you, a star system sacrificed. But even now, your greatest civilizations are doomed to fall. Your leaders will beg to serve us."

"Know this as you die in vain; your time will come. Your species will fall. Prepare yourselves for the Arrival."

"Shepard! I was just waxing goddamn nostalgic!"

"I hear we have a galaxy to save."

"No one said you could talk, jackass."

"[explaining how he survived a shot to the face] Rage is a hell of an anesthetic."

"[setting the person who fired said shot on fire] Fry, you son of a bitch."

"[If Shepard tries to touch an old rifle in his room] Hey, don't touch. That rifle's older than you are. I call her Jessie, that's my lucky charm. More men have been killed with that gun than in the Skyllian Blitz."

"[If Shepard allows Rana Thanoptis to escape the second time] That's going to bite you in the ass someday. [Rana Thanoptis is mentioned in the third game as being indoctrinated and killing five offcials with a bomb]"

"[recalling a previous mission] Everyone died but me, so I made out like a bandit. My first 'impossible' mission as an independent contractor."

"[After EDI reveals that the Collectors used to be Protheans, and Shepard declares his intention to continue opposing them] Damn straight! They're not doing that shit to us."

"[when the Geth Colossus fires at him] I get paid extra for anti-armor!"

"Doesn't matter who you are - you got a gun in your face, chances are good you'll do what the other man says. Only two types don't buckle at that point: trained killers and psychopaths. Lot of people can't tell the difference."

"Canned orders over loudspeakers. Classy."

"I'm the best thief in the business, not the most famous. Need to watch my step to keep it that way."

"Come back later. I'm sure I'll have more to talk about."

"My grandmother used to make the best ramen. Delicious. Thinking back, I really should have stolen her recipe."

"I must say. That Jacob? Mmmm..."

"[overlooking Illium] Towers, traffic, lights and asari everywhere you look. I thought about living here for a while, but everybody’s so tight-ass. It’s all about money to these people. I do what I do for the love of it. These people do it because they don’t know any better."

"How did Hock get Lady Liberty's head? Damn you, Hock!"

"[During Mordin's loyalty mission, after he mentions he can smell "a hint of dead flesh"] Well, I'm spooked. Thanks."

"[On Rana Thanopolis] She seems nice - in a mad scientist, ethics-for-sale kind of way."

"They're really selling the "Geth did it" message. I bet you can't even say "Reapers" without inciting a panic. [uses finger quotes] "Reapers!""

"[Overheard by Shepard after meeting her again on Illium] Have you ever faced an asari commando unit before? Few humans have. I'll make this simple: either you pay me, or I'll flay you alive - with my mind! [the client she was threatening promptly disconnects]"

"[Walking with Shepard on the side of the Shadow Broker's ship high above Hagalaz] Okay, looking down was clearly a mistake."
