Talitha

Talitha is a human former slave, who is located at the Alliance docking bay. She has stolen a pistol, claiming she wants to die. She is involved in the Citadel: I Remember Me assignment, and only appears if Commander Shepard has the Colonist background. Lieutenant Girard is attempting to defuse the situation.

Shepard is called by Lieutenant Girard to handle Talitha, who is at the docking bay threatening to kill herself with a pistol. If Shepard chooses to talk to Talitha, the Commander discovers she is a fellow survivor of Mindoir.

Confused and speaking in the third person, Talitha gradually tells her story. She was six when batarian slavers slaughtered her family, forced to watch her parents incinerated by their weapons. The young Talitha tried to hide from the batarians and hoped they would go away, but they captured her and implanted a control device in her head. She became a slave, mistreated and beaten even for crying, but Talitha gradually adjusted to her new life. Shepard believes Talitha developed Stockholm Syndrome over the years of her captivity. Eventually, Alliance marines raided the slaver encampment, killed the batarians and freed their captives. Talitha was so inured to her existence as a slave that she even tried to help her 'masters' after they had been killed.

If Shepard approaches Talitha too fast, she will shoot herself. However, if Shepard is careful, Talitha can be gently made to face her past, take a sedative and attend a psychiatric facility for treatment. If she refuses to take the sedative, Shepard can force her to swallow it. Alternatively, Shepard can decide she is too much of a threat, and give Lieutenant Girard the order for a sniper to kill her.

Trivia
'Talitha' is a Hebrew word meaning 'young girl' and also the Aramaic word for a maiden or virgin. The Bible recounts that Christ restored a girl to life by speaking the phrase "talitha kumi", meaning "little girl, arise" in Hebrew or "maiden, get up" in Aramaic (wikipedia article).
