At the end of the Citadel DLC, you’ll have Maya Brooks in custody, you’ll be given the choice to decide her fate.
Choice: Escape or not
When Brooks is in custody, you’ll get the choice “Don’t make me kill you” or “I want to kill you”. This choice can be important on the outcome for your squad members.
Choice: Don’t make me kill you
By choosing “Don’t make me kill you”, following it up with a Paragon interrupt will stop her from resisting, and she’ll go into custody peacefully.
Choice: I want to kill you
By choosing “I want to kill you”, or any other option, including missing the Paragon interrupt in the above choice, will result in Brooks breaking her restraints, this’ll leave you with a Renegade interrupt, leading to you killing her. If you miss the interrupt, one of your squad members will take a shot.
