I made the adjustment ;) But I think he would turn her away is this girl was the fiancee of someone close to him, a girl this someone close to him was prepared to die for. He wouldn't hurt Will, unless there was something more important at stake. Or, and I tried explaining this to metalkatt last night, Jack is seeing if Elizabeth is really worthy of will. A la Becky Sharp seducing George Osborne so that she can let Amelia Sedley know her husband was a loser, and she's free to love Will Dobbin. It's painful but its an act of compassion (as Bootstrap says about the flogging).

I think its abundantly clear that what she loves in Will is the pirate mystique. It bothers me that those two are going to get married (I'm almost certain of this *sigh*) In a perfect world, Jack would take Will aside and tell him she's not good enough. Will wouldn't believe him, so Jack would have to tell him that she came on to him to reals.
