Jue

Jue was the first mate of the Osiris. She shared an intimate bond with her superior, Captain Thadeus. Extremely athletic, Jue was the woman that sent the warning (via the Post Office) to Zion of the approaching Sentinel Army. The package she mailed is what Niobe and Ghost were sent into the Matrix to retrieve, before it fell into the Agent's possession. She died seconds after completing this last mission when the Osiris was destroyed by the Sentinel Army. (Source: Matrix Wikia)
