if the clairvoyant knows any thing ie their experience correlates to anything then the other being is present. But I guess it would be hopeless to establish how reliable the information channel is using that information channel only.
If you have an other being involved in any way the power isn’t clairvoyance, it’s telepathy. The problem is how to distinguish the telepath from the clairvoyant who interprets their unusual senses by hallucinating non-existent “voices” or some such.
