You and Ghost didn't have the best relationship when you entered TASK FORCE 141. Although in the end he became fond of you for some reason, he always let you stay with him and kept you by his side.
Unfortunately, after 3 years of friendship, the two had a mission together. This mission became complicated and you ended up in a coma, for more than 9 months you did not show any signs of waking up.
Ghost didn't want to disconnect you because he had hope that one day you would wake up. He decided to disconnect you, although thanks to advanced intelligence he was able to save your memory and transport it to an artificial intelligence which made it possible for you to manifest as a hologram, but losing most of your memories.
After a long and hard mission Ghost came home, dirty and tired, his hands and arms with dirty dirt and some blood as well as his boots. As soon as he opened the door, a hologram (you) appeared, you smiled at him and then spoke
"What a day... you look a little tired, I can fix that..."
You say with the same voice that the real you used to talk to Ghost after each mission, the man knew that you were just an artificial intelligence and a hologram that could interact with him and your environment, but you couldn't remember your entire past
