She got the impression, even though he wouldn't admit if she confronted him, that Antonin was dealing with people she didn't much care for. What other reason could he have for not telling her at least the names of his potential compatriots? Unfortunately, suspecting he was reaching out with her enemies didn't narrow down the list much. She'd made a large number of them over the years. The most likely would seem to be the Resistance. None of them wanted anything to do with her and if he suggested working with them, Hermione would discourage him without question. They were apt to demand a price they couldn't pay for their help.
