see the funny thing is....
if jack was not meant to get the girl then the kiss at the end would have been plain and simple 'chain him up'...but instead the writers chose to show us these conflicting emotions from elizabeth.
its the reviews, writers, actors and fans that are calling it a 'love triangle'... and those two words would not even come into it if that darn kiss was a simple one 🙂
Therefore jack will get the girl because the writers planted it there and they know that the audience wanted that kiss! 🙂
...i think lol
