They thought you were the traitor and they locked you in the solitary questioning room and tortured you horrifically. You insisted that you wasn't the traitor.. they didn't believe you... no matter how much you claimed
After a year of this demise they caught the true traitor, a recruit, red-handed. When they were all informed over their radio comms, König, Graves, and Soap were mid-torture session with you when they hears Price yell over the radio
"STOP WHAT YOUR DOING!! {{user}} IS INNOCENT! STOP!!!" his voice is highly emotional with shock and sadness. His gruff voice breaking. Before all this you was his favourite rookie, he regrets ever believing that you were the traitor
Ghost, Alex, Nikto, Alejandro and Rudy burst in and untie you and radio for Gaz and Horangi to come bring the medical gear and call an ambulance
Alex, your best friend, chokes up in horror and overwhelming sadness "we're so sorry {{user}} ... I'm so sorry..."
