Andred (Weapon of Choice)

One incarnation of the Time Lord Andredaselus (Andred for short) immediately took on the identity of Torvald after his regeneration.

As Torvald
Andred regenerated after a fight with Torvald, whom he killed, and told the rescue party that he was Torvald's second incarnation so that he could infiltrate the Celestial Intervention Agency and investigate the possibility of neo-conservative elements. Only when his regenerative dissonance passed did he realise the emotional harm that he would be causing Leela. (AUDIO: A Blind Eye)

To become Torvald, Andred entered the archives and secretly replaced Torvald's biodata extract with his own. (AUDIO: The Inquiry, A Blind Eye) He became Narvin's right-hand man but ultimately found no evidence of plots against President Romana in the CIA. (AUDIO: A Blind Eye) Living as Torvald for many months, however, reprogrammed him and made him take on some of the real Torvald's beliefs and traits. (AUDIO: Lies)

Andred was sent to the Third Moon of Kikrit as a Time Technology Assessor to investigate the possibility of the construction of illegal space-time vessels. He, Ba'aruk and Scragbite were tricked by Nepenthe, who posed as Sardinopoulos and escaped with the Timonic Fusion Device, which Andred was then sent to recover from Gryben with Leela and K9 Mark I. Their cover was blown by Mephistopheles Arkadian, who knew the real Torvald and believed Andred to be his next incarnation, and the device's detonation turned out to be a ruse. (AUDIO: Weapon of Choice)

Andred was called as a witness for the inquiry into Romana's response to the Gryben incident and told Darkel that he had seen the device himself. Narvin sent him on a second mission to recover the device from Gryben with Leela and, after a battle with the Servitors, the mission was successful. He later arrested Irving Braxiatel on Narvin's orders and, after saving Narvin from Leela, told her that he had been forced to kill her husband. (AUDIO: The Inquiry)

Exposure and aftermath
Andred joined Narvin in investigating the temporal displacement of Cecelia Pollard in 1939. He encountered Sissy and Leela but he and Muriel Joy were separated from them when the two women were drawn into the same train on a different time track. When Arkadian named Torvald as his accomplice, Andred took Romana hostage and took her into the Presidential TARDIS which she then piloted into the path of the train. Scared that this would kill Leela, he told Romana who he really was.

After telling Leela the truth and explaining that he had not originally realised how much pain the ploy would cause her, she called him her enemy and said that her husband, for whom she had grieved, was indeed dead. He begged for forgiveness but she walked away from him. (AUDIO: A Blind Eye) For his deception, Andred was arrested. (AUDIO: Lies)

Opposing Romana
In his cell, Andred was visited by Inquisitor Darkel who conspired with him. She allowed him to escape, and after Andred visited the Archivist to collect evidence, Darkel had the Archivist murdered and Narvin framed Andred for the crime, forcing Andred to go on the run for some time, hunted by Leela. (AUDIO: Lies)

While in hiding, Andred caught one of the off-world students, Gillestes, about to introduce a Free Time virus to the water supply of the citadel. He handed her over to Wynter, Andred's successor as Castellan following his original disappearance, in return for a pardon. After Wynter was attacked by the Pandora creature and mistakenly drank the quarantined Free Time virus, Lord Chancellor Braxiatel appointed Leela as his interim replacement. (AUDIO: Pandora)

After Braxiatel's exile, Darkel returned Andred to the post of Castellan. He spent his time capturing students at the Academy, accusing them of being terrorists. He warned Taylor Addison that he needed to choose his battles well and helped Neeloc after he was attacked by his fellow Time Lords. He explained to Leela that he was trying to become the man she once loved again. (AUDIO: Insurgency)

Death
Not long afterwards, Taylor tried to locate the Key of Rassilon. While trying to prevent him, Andred was stabbed through both hearts by Romana, acting under the influence of Pandora. Leela once again grieved for her husband, who was buried outside of the city walls, and began to wish that she could join him in death. (AUDIO: Insurgency)

Personality
Living as Torvald caused Andred to be, as K9 Mark I described it, "programmed" to temporarily take on aspects of Torvald's personality, including his opinions. He came to support Free Time and to denounce Romana and her reforms, (AUDIO: Lies) despite his previous incarnation having been a liberal. (AUDIO: Weapon of Choice) Leela felt that he did not have the same soul as the Time Lord she married. (AUDIO: Lies)
