A couple is getting married to close out this season of How I Met Your Mother.

Who will it be? Viewers will find out at the conclusion of the May 16 finale. But executive producer Carter Bays tells TV Line this reveal will simply lead into another mystery.

“The wedding takes place ‘a little ways down the road’ - an unidentified, unspecified amount of time away,” Bays teases. “We will be jumping forward for the last scene of the finale, but then we’ll return to the present day when we start Season 7... the idea is that we’re going to keep revealing little details about this wedding day as we build toward [it] within the chronological story of the show.”

As fans know, Ted meets the mysterious mother at this event - but Bays said the show's recent two-year renewal has allowed him and the staff to add this "new dimension." It will toss out such questions next year as:

Who is this woman that Ted’s going to meet? How does he meet her? Who is getting married? How will that couple arrive at the altar?
