A group of Northern Residents, from G clan, visited Nootka Sound yesterday. It is believed that Luna heard them, though he didn't join them. It is very unlikely that Luna would join a group of killer whales from a completely different community. The fact that residents visited Nootka Sound suggests a completely natural reunion is possible for Luna. Luna's presence in Nootka Sound suggests Southern Residents also visit Nootka Sound. If Luna hears them they may reunite on their own.
