By Hermione's third night in Draco's flat without him returning even once, she stopped worrying so much about him potentially betraying her to either side. Knowing that she was a proven flight risk, he wouldn't have waited so long to reveal her whereabouts to someone who wanted her blood. One thing she had always known about the wizard since their first year together as classmates in the castle was he was far from being unintelligent. In fact, there were many classes that he was a formidable opponent in the race for the top marks. He would understand just as well as she that he would have to move quickly to turn her over. With the exception of the time she spent within the Resistance's village and the days in Cornwall, she made it a point not to linger too long in a single area.
