I didn't get rid of Ansem completely, even when I fought him in Castle Oblivion. He might not even be entirely gone now - but if he's there, it's such a faint trace that I can't tell.

The darkness in my heart is still there. But now it's my darkness. The darkness that showed me the way when I was lost, and gave me the power to help my friends.

It's a part of my heart... nestled side-by-side with my light.
