Kate Beckett and Rick Castle are ready to take vows in the finale of Castle Season 6 'For Better or Worse' but there is a slight problem. It appears that Beckett is already married and needs to get a divorce from her newly discovered legal husband.
Just three days before the wedding, Beckett is shocked to discover that she is already married for 15 years to a bartender, Rogan O'Leary.
And like Castle, she too needs to submit divorce papers in order to exchange wedding vows with Castle. She suspects the wedding happened when she had a drunken rendezvous with Rogan in Las Vegas.
But will she be able to get a divorce in three days to marry Castle? What will happen to the most awaited Castle-Beckett wedding?
These questions and more will be answered during the finale of ABC's police procedural drama which will air on 12 May.
