Adult Simba:  I know what I have to do. But going back will mean facing my past. I've been running from it for so long.
  [Rafiki hits Simba on the head with his stick]
Adult Simba:  Ow! Jeez, what was that for?
Rafiki:  It doesn't matter. It's in the past.
  [laughs]
Adult Simba:  Yeah, but it still hurts.
Rafiki:  Oh yes, the past can hurt. But the way I see it, you can either run from it, or... learn from it.
