Happy Happy Joy Joy

I'm going to see Pirates for the second time tonight!!! And I'm going to see it again Sunday! You see, it is a great movie and the board of inquiry has these questions:
Was the kid at the beginning wearing braces?(I think so)
Who stabbed the heart, Will or Jack or Jack made Will?(I say last)
Boy or girl at the end after credits?(I thought really ugly girl, but everyone else says boy...)
Yeah. So. Anyway. Got to go! Fun Fun Fun!
