John Doe

• John Doe is a minor character in the short story; The ''Mona Lisa''.
• John Doe is probably the only survivor of the Flood infection of the prison ship, the ''Mona Lisa''. He is found by the crew of the UNSC ''Red Horse'' in a escape pod that originated from the ''Mona Lisa''. Sergeant Zhao Heng Lopez and his team open the escape pod to find John Doe laying in a large pool of his own blood.
• However, almost directly after the opening of the escape pod, John Doe rises up and stumbles to Sergeant Zhao Heng Lopez's team and screams "Don't let them get me!"

Injuries

• John Doe is later stabilized by Hospital Corpsman Ngoc Benti. A closer inspection of John Doe's body shows a huge hole in his chest, vicious and brutal slashes across his body, a blackened left foot in dire need of amputation, a chunk of flesh missing from his left arm, a shattered shoulder, and even a missing ear.

Last Moments

• In his last moments, John Doe is questioned by Sergeant Zhao Heng Lopez. John Doe thanks god for the safety the UNSC Marines provide. As the Sergeant questions which ship John came from, he is able to mummer "The ''Mona Lisa''."
• As John Doe gains strength, he asks Sergeant Lopez "You don't know, do you?" As he gains yet more strength, John Doe makes a joke, saying "This is where I'm supposed to say, tell my girl I love her, that sort of thing."
• John Doe soon explains to Sergeant Zhao Heng Lopez that he knows he is dying saying, "...I know I'm dying. But that's okay. I'm clean. I'm here. I won't come back. It's okay. It's all okay." These are John Doe's last words.
