Draco seemed sincere in his promise that he wouldn't betray her location. She hoped that she could trust him. Revealing to Antonin or even to Augustus that he knew she was there was dangerous. They would definitely see him as a threat that needed to be eradicated. She couldn't tell them why she didn't believe he would hurt her. His statement that he believed he was falling in love with her was difficult to swallow, but she did trust that there was some sort of connection between them. At least enough that neither wished harm on the other. It would have to be enough.
