Isilt spent a few days simply waiting for the right time to deliver his report, the way it had to be done was already decided upon, he had hidden the parchment within the horn of a corneau, which was a common gift for men to give women in the south, the idea was for him to deliver the good to a female soldier that like him, was hiding amongst her family, the mission of this soldier was just to stand-by to receive goods, so she was the least likely to be suspected.
And frankly, it was far from suspicious for anyone to give her this sort of presents, it was a shame that this would just be viewed as him fulfilling his mission, but he had to take his head out of the gutter and act as natural as he possibly could, he had first thought that delivering something so sensitive during the day was a bad idea, but the scenario that had been thought of simply could not work during the night, unless they wanted Isilt to get in the role of a rather creepy suitor.
