Harry's trust in Dumbledore is challenged here, and it made me wonder how much of our view of mentors is shaped by their secrets.

It added a personal touch to the story and deepened the mystery—I'm curious whether this was planned from the start or a later idea.

The tone shifts significantly, making the stakes feel higher. Did anyone else find this transition both exciting and unsettling?
