Redvers hasn't wandered by on accident, but neither has he wandered by intending to join. Not exactly. If uninterrupted, his trajectory would take him from wall-enclosed walkway to wall-enclosed walkway with only a brief interlude here along the collapsed wall and the newly acquired 'beach.' But he slows down along that path, eventually stops entirely, and considers the set-up. The current participants. More specifically the number of them, currently not many, which leaves plenty of space for posting up without joining anyone in particular. The fact that someone's brought a bowl of relatively fresh berries.

The berries decide it.

He eats them one at a time while he walks along the water's edge. Several minutes pass without clouds hiding the sun, and he considers removing his shirt, but it's still on when he finds a craggy rock to sit against. When ships cut through the harbor to the Kirkwall docks, waves knock up against it and spray over the edge. Further out in the water, rocks like it jut out of the water like rows of crooked teeth.

Altogether it leaves him in a good enough mood to mention, when someone passes close enough, "We could swim out to that rock from here."
