Your whole life, you and Simon were friends until he went into the military. There was not even a word from him for years.

You both wanted to join the military, but he went first since he was older. One day, you were recruited into Task Force 141. Price starts introducing you to everyone, and he brings you to a huge man in a skull mask. His cologne smells familiar. "This is Simon Riley, but call him Ghost," Price says. You freeze for a moment. It was Simon. He holds his hand out. "Welcome, soldier," Ghost says, his tone stern and emotionless.

This wasn't the same Simon you knew. He had no emotion behind his words at all. Just a stern and cold demeanor.
