Legion/Unique dialogue

On occasion when Legion is in the squad, it will engage in conversations unique to it.

Unique Dialog
Throughout Shepard's travels, there are specific points where Legion will voice its opinions.
 * On the Citadel, when talking to the C-Sec Customs Officer about the high level of security, the officer explains the new security protocols against geth infiltration, Legion notes that geth do not infiltrate. The Officer, oblivious to it being an actual geth, then tells Shepard that their "personal synthetic assistant" is not allowed on public shuttles, forcing Legion to admit not to infiltrate intentionally. (Which is ironic given that Legion's initial class is Geth Infiltrator.)
 * If brought along during Shepard's first visit to the Citadel, Legion will humorously mention that "metal detectors are inconvenient" when the turian C-Sec officer explains how the scanners think Shepard is dead.
 * On the Presidium, during the Council meeting when Shepard asks them to investigate Sovereign's superior technology as proof of the Reapers' existence, the Salarian Councilor will state there is no proof that Sovereign was not of geth origin. Legion will retort that the geth do not have that kind of technology. The salarian dismisses this, labelling Legion as Shepard's trophy and saying that its word is suspect.
 * On the Presidium, when asking Captain Anderson about the war with the geth, Anderson will remark that Shepard's "trophy-bot" hasn't caused a stampede among the general population because the war with the geth is winding down. If Shepard tries stating that some geth can be reasoned with, Anderson warns that it's best not to get into another fruitless debate with the Council.
 * During Tali's recruitment mission, Kal'Reegar will notice Legion and inform Shepard that they've got a geth behind them. Legion will inform him that he will combat these geth, which Reegar says he will only accept because he can't afford to be picky. Upon finding Tali, she will shoot at Legion unless a paragon interrupt is used, causing Legion to take cover and request assistance against friendly-fire.
 * On the Migrant Fleet during Tali's loyalty mission, Legion will be held at gunpoint by quarian security. Unless Charm or Intimidate is used, Legion will be sent back to the Normandy SR2. (Ironically, Tali is being charged with bringing active geth into the Migrant Fleet; bringing Legion, one would think, would be the equivalent of admitting guilt.) It also triggers different dialogue with many of the Admirals.
 * Daro'Xen will be fascinated by Legion and wish to study it, to which it responds "This platform is not available for experimentation". It also judges Xen's plan to re-enslave the geth as "unsound", to which Tali agrees.
 * While talking to Zaal'Koris, Shepard can ask Legion if a peace can be made between the quarians and geth. Legion responds that it will seek peace only when it receives more data that a truce is what the quarians truly seek, as the only other time the quarians believed they held an advantage, they attacked.
 * Shepard can tell Han'Gerrel that there are different factions of geth, but Gerrel doesn't care much, simply hoping the geth can kill enough of each other for the quarians to take back the homeworld. It is notable that no one on the Migrant Fleet seems at all surprised that Legion, a solitary geth, can talk.
 * In Rodam Expeditions, using the Renegade option to get a discount prompts the salesman to request a geth's head to make into a desk lamp. Legion notes that functionality is not in the geth's specifications.
 * During Samara's recruitment mission, Legion can be asked about its opinion on drugs, upon which it compares it to overclocking, which provides short term improvements at the expense of possible long-term damage. Legion notes that while geth can easily repair damage caused by overclocking, organics cannot, leading to it questioning why they would engage in it. When asking for access to the crime scene, if Shepard suggests not following the order to arrest the Justicar, Legion will note that they are ordered into deadly situations "an average of 2.73 times daily. Rounding down."
 * There is a minor joke in a dialogue with Legion on its loyalty mission. If you choose to rewrite the geth heretics, Legion states that the resulting electromagnetic pulse with a power of "1.21 petawatts" will be deadly to team inside the base. This is a reference to Back to the Future.
 * If Legion is chosen to lead the second diversion squad during the Suicide Mission, it will end up dying after being hit by a Collector attack. Its final words are "Barriers overwhelmed. Auto-saving. Archival upload commencing. No carrier. No carrier. No carrier. No-".
 * If Legion is carried away by the seeker swarms, its final words are "Critical error. Error!".
 * When the decision is presented to preserve or destroy the Collector base, if Legion is present, it voices an opinion that seems to be in favor of preserving the base. It indicates that the base is "data only" and that destroying it will not bring those who died back, but saving may prevent further deaths. However, the base is preserved and Legion survives and is spoken to after the Suicide Mission, it becomes apparent that it was simply stating logical observations and is in actuality against using the base.
 * In the Overlord DLC, when Dr. Archer meets Shepard, if Legion is present, Archer asks Shepard if Legion can be trusted. Shepard replies that Legion cannot be brainwashed by other AI.
 * During Jack's Loyalty mission, Legion's response to the cruel acts done to children in the lab as it sees the living conditions as "THESE﻿ FACILITIES ARE INADDEQUATE."

Talk to Squad Mate

 * Citadel : Zakera Wards Level 27 behind Avina, Legion will state that the station is not unlike their own &mdash; it is inefficient since organic shells require more space. Legion will then begin an extranet search of other hive species in an attempt to understand.
 * Illium: At a trade station next to the volus shorting on Prefabs, Legion notes that the Council races find slavery abhorrent, but no one questions the limits placed on EDI.
 * Omega: In the lower level of Afterlife, Legion, unaware of the partying nature of organics, will question why anyone would wish to willingly poison themselves with alcohol, damage their ears from the venue's loud music, or contract sexually-transmitted diseases.
 * Tuchanka: At a pile of rubble near the Chieftain's throne, Legion will comment on how the krogans nearly destroyed their own world and the damage is far greater than the damage the quarians caused during the Morning War. If Tali is in the party, she says her people intend to retake their homeworld once the geth are wiped out and any change in the planet's environment would mean that they would have to search for a new planet to inhabit. If Grunt is in the party, he will say that he wouldn't expect the geth, or any alien, to understand; Legion retorts that the destruction of a world is factual, perception does not change that.
 * Tuchanka : If Urz is injured during a fight, he can be found in the science tent behind the arena. Legion will remark about how organics treat 'lesser-evolved' beings inconsistently.

Spontaneous
Sometimes Legion will say something spontaneously, without being prompted.

Secret Dialogue
Secret dialogue cannot be normally triggered due to the game's plot advancement requirements, and is only accessible by manually editing Legion into the player's party at a point before it would otherwise be obtainable.


 * On Purgatory, when using the Renegade options to recruit Jack, when Shepard warns Jack she doesn't want to be Shepard's enemy, Legion will note that "There is a high statistical probability of death by gunshot. A punch to the face is also likely."
 * Also on Purgatory, when approaching the guard overseeing the inmate being tortured, Legion will question the efficiency of such tactics, claiming that "The subject will invent fiction it believes the interrogator desires. Data acquired will be invalid."
 * Also on Purgatory, when finding the dead guard during the prison riot, Legion will discuss how ineffective Purgatory would be at maintaining order if not for the security systems installed. "The guards are heavily outnumbered without the force multiplier of automated security systems."
 * On Omega, if Legion is in the party just before heading into the quarantine zone, he will say "This platform is immune to organic disease."
