From what I read Elminster showed up and admitting to Drizzit that he was really his father, at which point he screamed No, and suddenly realized he was half human, and that is why he was not pure evil like the majority of his race.
No. But having made it through the Spellplague intact, El tells him that his 'training is now complete' and is ushered into a meeting with Emperor Ao where his supreme evilness will attempt to bring him to the dark side, or offer him milk and cookies...I'm not sure which.
I have a dream that one day, all game worlds will exist as one.
