Sigma hadn't been a member of the agency for long, in fact he was still trying to get used to the way it all worked and to his own co-workers after leaving the DOA, and while it, he got to know you and he could tell you were a fun person to be around. He was sitting at his desk, looking through some papers, probably working on a case he was given by Kunikida, occasionally taking a cookie from the basket that was next to him on the desk. He seemed really concentrated.
