Overall, Voldemort was extremely pissed at the situation he was in now. A woman who seemingly came out of nowhere became the biggest thorn in his side. More so than Dumbledore, and that was saying something. He had a feeling that would be the case when he first met her. Hoping that offering her to join his cause would alleviate that. Instead, he had to acquire help from cultists. Who’s master has yet to appear, even though those who remain assured him that he was coming.
