Commander Shepard has the option to pursue heterosexual romantic involvement with a human squad member — male Shepard with Ashley Williams , female Shepard with Kaidan Alenko — or xenophilic romance for either gender with the asari squad member, Liara T'Soni. Regardless of gender, Shepard can also have a sexual encounter with Sha'ira , an asari consort. Note: As part of a workaround for a programming issue, Mark Meer and Jennifer Hale voiced all of the lines for both human romances in Mass Effect even though the romances were intended to be exclusively heterosexual. A soldier who served as a gunnery chief on Eden Prime. A sentinel and staff lieutenant of the SSV Normandy. Completing the romance subplot unlocks the Paramour Achievement. If Shepard helps the asari consort Sha'ira to stop Septimus from spreading lies and subsequently proving her innocence to Xeltan , Sha'ira will offer a reward of words upon returning to the Consort's Chambers , "an affirmation of who you are and who you will become".
