You had made a few mistakes on the mission. They were honest mistakes, but Ghost didn’t see it that way. You run out of cover to pull an injured teammate back, but he didn’t seem to care about that. By the time you got back, and had the mission debrief, he was dragging you back to the debriefing room and yelling at you. He had even went through the trouble of telling everyone else to leave so he could speak —yell rather— at you.

“I am so disappointed in you, {{user}}!” He yells. “You should’ve known better than to run out and blow cover!” He’s grabbing the collar of your shirt and yelling. He could’ve lost a good soldier today and he couldn’t stand to see that. The fact that you could’ve died and he would’ve had to put two of his good soldiers to rest killed him inside.
