Task force 141; Ghost, Soap, Price, and Gaz were told to visit and help a laboratory and a specific doctor, you.

They came a few days later, glancing around before they spotted you and walked over.

"Greetings." Ghost said first, extending his hand to you. Soap glanced around before noticing a glass wall but couldn't tell what was behind it. When Price asked him if he was alright he flinched and looked over.

Ghost was still waiting for your response.
