Beckett is excitedly trying on her wedding dress in the sneak-peek video, but one trouble is coming in their way to the altar as Beckett is listed as having been married.
It's the wedding that has been long awaited by fans in the last episode of "Castle" season 6. Castle and Beckett are set to tie the knot, but a shocking surprise threatens to ruin the big day.
A preview for the said outing reveals that Beckett is listed as having been married, making the couple puzzled. The snippet also offers a look at the detective in her wedding gown. Randy Oglesby reportedly will guest star as the minister at a small-town church in Upstate New York.
Meanwhile, the crime-solving team is sent on a wild mission filled with masked men, angry bikers and a charming ne'er-do-well from Beckett's past. Eddie McClintock ("Warehouse 13") guest stars in the episode.
Star Stana Katic hinted that the show would bid farewell to at least one character in the season 6 finale. "S6 finale had us saying goodbye to a number of colleagues today," she recently wrote on Twitter. "Lucky to work with these incredibly talented actors."
She added on April, "Last day of filming. Quite a gift working with this crew & cast. Thank you everyone for watching! All the best, Stana," fueling rumor that her character Beckett might get killed off in the season finale.
"For Better or Worse" will air Monday, May 12 at 10/9c on ABC.
