One of the refugees, a former shinobi allegedly from Kirigakure, was summoned by the Iwagakurian government to handle one of their missions, as per the general agreement for taking refuge within their city -- that those who are still able-bodied would be provided with assistance in settling, along with compensation and needed resources to survive. Two others were summoned to join in this mission, in addition to the refugee, one another traveler from Konohagakure, and one a native to Iwa. We'll get to the other two a bit later.
The shinobi was provided with a notice early morning, alerting him only that he had to come to the Embassy for a debriefing at sunrise. Assuming Katsumi had awoken when he got the letter, he would have four hours to prepare and arrive. The room at the Embassy he'd go to was a small one: it was a carved-in conference room known as the "Office" -- as it was the only one -- which was able to easily fit five or so people and provide them with ample room to move around within.
