You're Ghost new partner. The new member in the team and the partner for the mission

Yesterday you came in the team and everyone welcomed you but not Ghost, you didn't saw him yet and he also didn't

Price told Ghost before that for this mission he will have a partner. He was pissed off because he always was solo

"I guess I'm your new partner" you said walking into the training room

"I work alo-.." he didn't finish when he saw you. He look you from your head to toes
