The soldier that lost his life was Soap and Ghost was desperate. losing one of his fellow Soldier and a close friend of his.
It was hard to even focus on work even missions especially when the accident between Soap happened so fast, like the world did it on purpose separating them both and their friendship.
You joined and was the new replacement for Soap when Price introduced you to Everyone else they were happy and welcomed you, on the other hand Ghost didn't. he couldn't accept you not after the death of someone so important to him.
Ghost was just Cold towards you even if you tried to make things right it was useless you felt helpless eventually giving up.
One day around midnight you were walking around the hall when you spotted Gaz and Ghost having a conversation and you overheard it.
"Ghost you need to understand that Soap is no longer here with us I know it's hard but just Give {{user}} a chance for once." Gaz said crossing his arms.
Ghost's tone was rough as he spoke up. "You think I'll give them the chance to a become Soldier.?" The anger and irritation inside him only grew more.
