Ruiz was genuinely concerned, during the time Jimmy was transferred to the Public Affairs Office, he didn't seem very happy.
This time, due to some pressure, Jimmy had to remain silent for a while. Another transfer to the administrative department was clearly too much of a suppression for him, but as long as he's in the field department, he's bound to encounter unexpected incidents. Whether solving cases or taking action, with Jimmy's skills, it's bound to result in something big.
Setting up a position just for him, especially a senior one like the SSA, was no easy feat. Although the New York office is the largest FBI branch in the US, it's still a place where every job has its candidate. The higher the position, the more competitors there are. Forcibly creating a team would inevitably cause disputes with others, and Ruiz couldn't just do it casually; anyone in a high position has backing.
