What kind of impressed me about "The Truth, part 1" was the reveal.

Consider: In most mystery novels, the reveal scene(s) is where the detective explains what the reader has been struggling to figure out since the start of the story. It provides a powerful "ah-ha!" moment if done right.

Here, everything Harry figures out is stuff the reader most likely already knew, thanks to meta-knowledge. We're watching him figure out what we'd been hoping he'd figure out for dozens of chapters. By all rights, it shouldn't provide that ah-ha feeling.

And yet... it does. I think the stream of consciousness really sells it. It helped me feel like I was inside Harry's head, living through that realization.
