What do Harry's group and the men with Jack do after they eat breakfast and what does Jack think about where they are going and what is Senay's response to his concern?

After breakfast, two dozen Outlander soldiers follow Harry into the Hills. When it is announced they are heading to Senay's village, Jack notes that the Outlanders may not be welcome, but Senay, surprised, replies that they are comrades. Senay also notes that they are similar, too, in that they all follow Harry.
