Harry Potter and the Deathly Hallows
How we cite our quotes:
Harry could not help wondering whether [Ron and Hermione] had only agreed to come on what now felt like a pointless and rambling journey because they thought he had some secret plan that they would learn in due course. Ron was making no effort tot hide his bad mood, and Harry was starting to fear that Hermione too was disappointed by his poor leadership. (15.31)
The pressure's on for Harry and, like anyone else, it makes it harder for him to make decisions. But how can he possibly direct this journey when he doesn't even know what he's supposed to be doing? Choices are hard to make when there are zero viable options. Who knew? But this is the first real test for the group's perseverance and determination, and they all suffer from the lack of direction.
The rain was pounding the tent, tears were pouring down Hermione's face, and the excitement of a few minutes before had vanished as if it had never been, a short-lived firework that had flared and died, leaving everything dark, wet, and cold. The sword of Gryffindor was hidden they knew not where, and they were three teenagers in a tent whose only achievement was not, yet, to be dead. (15.106)
This moment, right before Ron's angry departure, is the lowest point in the journey; nobody knows where they're going or how they're going to get there, and it seems like no possible resolution is in sight.
"[Dumbledore] knew what he was doing when he gave me the Deluminator, didn't he? He – well," Ron's ears turned bright red and he became engrossed in a tuft of grass at his feet, which he prodded with his toe, "he must've known I'd run out on you."
"No," Harry corrected him. "He must've always known you'd always want to come back." (20.9)
Harry gently turns around the shame that Ron feels about leaving– as Dumbledore knew, Ron's loyalty is undying, and even though he seemed to give up, he'll always want to come back to his friends.
