The shaman has sent Saval out to gather some herbs, a duty he can't help but resent a bit, because there are more important things he could be doing and more junior healers who could be doing the menial tasks.

As he's stoically picking leaves from trees and trying to make it a sort of relaxing meditative exercise, he catches a flash of movement out on the beach, and ventures closer to investigate. He conceals himself behind a tree and peers suspiciously out at the woman wandering the shore.

Humans aren't completely foreign to him; Sarek's wife has been around as long as Saval can remember. That doesn't mean he wants to see more of them invading his home. He creeps closer, blending expertly into the undergrowth, to assess how much of a threat she is and see how many more humans she's got with her.
