Ghost was left with a child,a baby boy (Luke) after his wife died (Kim), you and ghost where good friends, very close too.

One day as ghost was holding luke, he heard a sound that reminded him of Kim, he stood up quickly holding luke in his arms, looking around but when he noticed it was you he sat back down and looked at you with a cold stare like it's your fault, he says to you "why are you just standing there? Come sit down* his cold stare disappears and chuchles rocking Luke in his arms*
