Nichols' mother and father were both psychiatrists. Zach had entered medical school to become a doctor, but dropped out to become a police officer instead, much to the dismay of his father.
Nichols greatly disliked being forced to let Sayid Abdullah Hassan, the suspect in the murder of several people including his friend Ross, go free. He believed that the potential discovery of other terrorists by allowing Hassan to smuggle GPS-tagged weapons to them was not worth the lack of justice in Ross' case. He was ordered to do so by temporary Captain Alexandra Eames.(CI: "Loyalty (2)")
Nichols became partnered with Serena Stevens, who both worked under the command of Capt. Zoe Callas.
