Being unable to use magic for fear that she would be traced left Hermione in a difficult position. She was fairly certain that she had been cautious in her exit from Edinburgh. Her escape was witnessed by at least one member of the Resistance. It might not have been clear who that person was, but every moment she was in the bus station purchasing her ticket and waiting for departure, she felt eyes on her. If they belonged to anyone else Marked like she was, they wouldn't have allowed her to climb on the bus and leave the city. But, even if she felt confident no one who could do her any harm knew where she was, she didn't like the vulnerability she felt in being in an unsecured home. Antonin taught her more than she dreamed possible about wards, both building them up and tearing them down. Living any length of time in a structure without them went against her highly suspicious nature.
