As if the alternative was better. Who knows how much Vladimir knew about the rumors and how seriously he would take Kon's. The longer Kon waited, the likelier Vladimir would think the rumors were true. But he tried not to become too paranoid. There was always the possibility Vladimir didn't know (and that's why there was no message about it) or that he did know but didn't think Kon did or should care about it.
Either way, Konpeitō called Vladimir up, wanting to talk with him in private. He gave the summarized version of his concerns: weird rumors were floating about the islanders and now he was part of them. Vladimir was such a good guy. He was willing to talk as soon as they were both free, at his house.
The next day, Kon rang Vladimir's doorbell. After taking the time to recompose, he was able to discuss the situation with a clear mind.
