Light Yagami is finally caught and exposed as Kira, but even at the end, he still sees himself as a god, too powerful to be stopped, even as everything falls apart around him. The notebook pushed him into obsession and power, as he keeps justifying everything he has done. He sacrificed so many lives along the way, including his father and colleagues, showing he has no real attachment to anyone.
The episode is quite long and heavy on explanations, which slows the pace, but it also makes everything feel more final and detailed. Even when caught, he still tries to eliminate those around him, like he would rather die than lose. Overall, it ends with the feeling that he still believes he is Kira, almost like the story could continue with him coming back.
