Price thought he lost you. on the last mission which was suicide mission Price lost his connection with you, however he tried to connect the radio but he failed, he then told to the task force that he lost the connection.

weeks passed, you were still not there, Price was feeling hopeless and went outside of his office hoping he would return you but he knew damn well it wouldnt work.

Price with the task force were talking until Ghost saw something infront of the gate which was you.
