Miranda will return in
Mass Effect 3, provided she survived the events of Mass Effect 2. After the mission on
Sur'Kesh, Shepard gets a message from Miranda asking to meet on the Citadel. Miranda expresses her concerns that her sister Oriana had been found by her father. If she is in a romance with Shepard, Miranda shows that she was greatly pained when Shepard was detained on Earth, and almost thought to break in to see him. If certain decisions are not made to warn her of a Cerberus attack, Miranda will later be killed by Cerberus Assault Troopers, under orders from the
Illusive Man. To keep Lawson alive read the dossier on Leng from your mail console, then read the mail that Miranda wants to meet for the second time. Go meet via video conference in the Spectre office on the ambassador level of the Citadel. Warn her about Kai Leng.
She is later encountered on
Horizon after Cerberus retrieves the Protheon VI from Thessia. Shepard quickly finds that Oriana is indeed being held by their father, who is operating a Cerberus facility disguised as a shelter called Sanctuary. Miranda is seen in recordings throughout the mission warning civilians of her father's true intent. Finally, Henry Lawson, who is holding Oriana as a human shield, comes face to face with both Shepard and Miranda. Shepard is either able to diffuse the situation diplomatically or to simply shoot him. If Shepard allows Lawson to leave, Miranda will refuse, using her biotics to push him out of a nearby window. Miranda, who was badly injured during a running battle with Kai Leng, dies in the company of Oriana and Shepard if she was not previously warned about Kai Leng's return to service of Cerberus. If Miranda's loyalty mission was not completed in Mass Effect 2, Kai Leng will mortally wound her even if warned.
Also, if Shepard cannot persuade Lawson diplomatically and does not shoot him after diplomacy fails, Miranda will take the initiative to kill Lawson herself, but Lawson will manage to get in a shot that fatally wounds Miranda, causing Miranda to die even if Miranda was warned about both the Cerberus attack and Kai Leng's return to Cerberus.
If Miranda survived those events, she tells Shepard she had the time to place a tracking device on Kai Leng during their short encounter, allowing the resistance to find the Illusive Man's location. Miranda then leaves with her sister, and asks Shepard to be careful.
She will join the
war effort and Shepard will have the chance to talk to her on Earth one last time, right before the final assault.
[h=3]Romance[/h] Upon meeting Miranda on the Citadel, a male Shepard has the chance to confirm his love for her. She says that things would never be simple for them. After helping her by warning her about the various dangers she could be exposed to, Miranda asks Shepard to meet her in a private room on the Citadel. There, she explains that she feels guilty, because she wanted to incorporate a mind-controlling chip within Shepard's new body while working on the
Lazarus Project. She mentions that the Illusive Man refused, in order to keep Shepard as close as he was to his former self. She despises herself, knowing its what her father would have wanted done, and she tells Shepard she's deeply sorry. Shepard has the chance to comfort her, which will result in the romance sequence with Miranda.
During the final mission on Earth, if Shepard previously romanced Miranda, she comments that this is farewell, while Shepard tries to be positive and promises to come back.
