So I was looking at all my old bookmarks for this pairing and something nagged at me.
There was this one story that had Norrington on the pearl. For some reason he was going to get whipped (flogged?) but Jack was going to pretend to do it as long as Norrington faked getting hurt. Which he didn't so Jack had to actually hit him.
Annnnnd that's all I remember. Any help would be appreciated!
