"Why is her range of hands so narrow? If its a flush, why can it only be A K ? She open raised from the cutoff."

And didn't cap pre-flop, but did cap the flop. So I agree, she might have a range of flush holdings, perhaps even something like J [img]/images/graemlins/club.gif[/img]T [img]/images/graemlins/club.gif[/img], considering she capped the flop and raised the turn.
