Since the No Russians mission and the loss of Roach, Ghost has never been the same.

You rarely saw him in his free time, he avoided talking to others, he didn't eat or sleep well and he was almost always training, oversaturating himself.

One day, Ghost was training, as always, punching a punching bag until his knuckles started bleeding, he had tears in his eyes.

He missed Roach, and you knew it.
