To set out the scenario, A group of divers being led by a local guide drop onto a plateau at 35m. We are diving an island 8 hours from land by liveaboard. There is strong current and surface swell The dive plan involves us hanging briefly on a plateau at one end of the island watching the blue before turning and making a multilevel drift with the current back to our liveaboard which is moored at the other end of the island. On the plateau a diver appears alone. He is overweighted with a massive amount of air in a ludicrously large wing for singles keeping him approximately neutral. Other than slightly inaappropriate equipment and a lack of buddy he appears calm and shows no intention of surfacing to look for his missing buddy/dive group but rather keen to join our merry band along the wall (all dive groups would be forced by conditions to dive this plan). What would the appropriate course of action be?
