so in the whole "we have to duplicate the events of the first flight" theory...
locke is a proxy for jack's dad.
is sayid being in cuffs to reproduce kate's situation in the first trip?
did hurley bring a guitar for charlie?
when jack and kate made fuck, did jack knock up kate so she could "proxy in" a baby to replace aaron? (and duplicate claire?)
ben late to the plane just like hurley was?
