Female soldier (The Blood Line)

This Female Soldier belonged to a unit led by Captain Federico Santos. They were sent to aid Rex Matheson and Esther Drummond in stopping the Miracle in Buenos Aires, Argentina. One of her comrades was an agent of the Three Families. When the soldiers were in a van, she noticed one praying in Spanish. That soldier set off a bomb. It destroyed the van, everyone inside and Jack Harkness' mortal blood, which was vital to stopping the Miracle.

She became a category one shortly before the miracle ended, when she presumably died. (TW: The Blood Line)
