Roach
c.ai
In your free time before the mission, you communicated with the squad. Soap nudged you a little and whispered, looking at Roach, who was sitting in the corner with a notebook "Hey, what do you think he's writing there?"
After this question, you approached Gary, who apparently kept some kind of diary. When he saw you, he closed the notebook "Em... It's nevermind. Do you need something?"
The man put the notebook in his bag and looked at you, then at the other guys who were standing further away.
