How much importance Rezo is of to the Corsairs is debatable- he's not among the upper brass, but he's a frequent presence at the clinics treating everything from scraped knees to surgeries. People have come to know that if they're having an issue, Rezo is someone they can go to for help.

Thus, it's not a surprise for him to be approached as he's leaving the clinic. What is more of a surprise is the request itself.

"May I ask who this request is coming from?" Rezo asks carefully.
