The day How I Met Your Mother fans never thought they would see is coming — Barney is getting married “a little ways down the road”!

It will, however, take quite a journey for the all-but-confirmed bachelor to get there, one that will revisit his past with Robin in “complicated and juicy” fashion, executive producer Craig Thomas tells TVLine. And Barney is not the only one who will be on a new path, as we learned in Monday’s season finale. After a rough year, Marshall and Lily are expecting a little Marshmallow or Lilypad, while Ted has finally blown up The Arcadian and his relationship with Zoey. Lucky for us, Thomas was kind of to offer up some teases about what it all means for the CBS comedy’s Season 7.

Given some of his issues, Barney getting married suggests quite a change for the character. Will we see a very different Barney next season?
We don’t know when this wedding is taking place. … We’re threading the needle on that [in Season 7]. How does Barney get to that place? What changes him? What makes him want to do this? Who’s he marrying? How did they get there? What’s going on on that wedding day? Is he happy? Is he nervous? Is this going to go forward? Is it going to be a disaster? … I will tease that in November sweeps of Season 7, where there will be four huge episodes for Barney. It will involve Robin, and there will be some very explosive relationship stuff happening.
