This unnamed Drazi met John Sheridan briefly during his imprisonment by Earth forces during the Earth Alliance Civil War.[1]
History
When John did not break under torture, this Drazi was ordered to provide an alibi for Sheridan. The purpose of this was to give Sheridan an out and encourage him to sign a confession. The Drazi expressed his fear and uncertainty and Sheridan encouraged him to keep fighting. He promptly refused to cooperate and was carried out on a stretcher and electrocuted - or so it seemed.
Later, after the captain continued to refuse to cooperate he was led out, apparently to his death. Then, he saw the executioner dressed in black - who turned out to be the same Drazi - before being put into another room with a different interrogator.
It is unclear whether or not this Drazi was part of the Earth regime or actually a resistance agent who arranged to save Sheridan.
