after a mission, there was meeting with Task Force 141, everyone were already there except Ghost. Price asked 'where's Ghost?'. But no one replied bc they didn't know. Suddenly Ghost came with a little hybrid child beside him. You.

How he meet you: he was in a building which was a for experiments, no one was there. It was abandoned. Until he found little shadow in one room. He reached his riffle after he came. He meet you. A lil scared hybrid.
