Commander Shepard 
- It's not the severity of punishment that deters criminals - it's the certainty.
Captain Kirrahe 
- We are trained for espionage. We would be legends, but the records are sealed. Glory in battle is not our way. Think of our heroes: the Silent Step, who defeated a nation with a single shot. Or the Ever Alert, who kept armies at bay with hidden facts. These giants do not seem to give us solace here, but they are not all that we are. Before the network, there was the fleet. Before diplomacy, there were soldiers! Our influence stopped the rachni, but before that we held the line! Our influence stopped the krogan, but before that, we held the line! Our influence will stop Saren. In the battle today, we will hold the line!
- Asari Councilor: Commander Shepard - step forward.
- Asari Councilor: It is the decision of the Council that you be granted all the powers and privileges of the Special Tactics and Reconnaissance branch of the Citadel.trim
- Salarian Councilor: Spectres are not trained, but chosen. Individuals forged in the fire of service and battle; those whose actions elevate them above the rank and file.
- Asari Councilor: Spectres are an ideal, a symbol. The embodiment of courage, determination, and self-reliance. They are the right hand of the Council, instruments of our will.
- Turian Councilor: Spectres bear a great burden. They are protectors of galactic peace, both our first and last line of defense. The safety of the galaxy is theirs to uphold.
- Asari Councilor: You are the first human Spectre, Commander. This is a great accomplishment for you and your entire species.
