It was tempting for Hermione to cling to his promises as fact. When he spoke of running from the Dark Lord's influence permanently, she could think of nothing else that she wanted more. After being alone for so long running, the idea of having someone there with her was appealing. She might have been willing to throw caution to the wind for no other reason than because she was tired of being alone. Having another person to lean on, bounce ideas off of, and share in the adventure or the danger might make the meaningless existence she'd been living for so long the slightest bit better. What was the Muggle saying? A problem shared is a problem halved. Running with Augustus filled her both with excitement and dread. It would never work.
