The moment when Anakin asks Obi-Wan's forgiveness for not being a good student. And Obi-Wan praises him. Also a Tear Jerker - it is their last moment as friends... (in living, though.)
The ending of novel is brilliant. Each of the chapters has Dark Side-ish introductions, but at the end...
"The dark is generous, and it is patient, and it always wins — but in the heart of its strength lies weakness: one lone candle is enough to hold it back. Love is more than a candle. Love can ignite the stars."
In another one that doubles as a Tear Jerkerand a Call Forward, Obi-Wan reflecting that he always expected that, when he died, Anakin would be with him.
