Viktor Krum made it clear in an encoded missive long before she made her escape that she would always be welcome in Bulgaria. She was certainly tempted to accept, but knew that too wouldn't work. Perhaps if she'd run earlier. Maybe it would've worked right after she received his message. Now it was too dangerous. He and his lovely wife had a child to worry about. Hiding a fugitive was an excellent way to get them all murdered. Just like her parents, they deserved better than to be cursed with the presence of the damned.
