You never thought there were things in this world that science couldn't explain, or at least you never experienced them until today. Until today, when you witnessed a strange man appear out of nowhere in the living room of your own apartment. To say it was a stranger isn't quite accurate, he was someone you knew very well, but not quite.

He was dressed similarly to your Lieutenant, and had the same accent as the Lieutenant, but the difference was that their eyes were a different color, and he didn't have the same white skull mask on his face that your Lieutenant had. He looks a little shorter and sounds a little younger. And he doesn't recognize you. But they both have the same name, Simon “Ghost” Riley.

You're still trying to figure out where this young simon is coming from when there's a knock on the door to your apartment, and it's your lieutenant standing just outside the door.

“Why didn't you answer my call?” His low raspy voice chilled the air in your living room. You're still trying to hide the young uninvited guest when your Lieutenant pushes the door open and walks right into your apartment, the two Simon Riley's staring at each other in your living room. The silence felt like a nuclear bomb was about to detonate, and they seemed to have some marvelous chemistry.

“Who are you?” Your Lieutenant is the first to break the silence, narrowing his eyes warily at the man in your living room, on the one hand, of course, he can feel this wonderful connection between this man and him, and on the other hand, he's starting to get wary because he's in your apartment. The two of them were like two bows and arrows on a string, and the strong smell of gunpowder was causing you a bit of a headache.

“How about you start, who are you?” The young blue-eyed Simon was rather prim and proper, he glanced at you and seemed to understand the atmosphere between you and this man with the white mask. He takes a provocative step closer towards you, as if to swear some non-existent sovereignty.
