5. Barney and Robin are getting married
Season 9 is the story of the weekend of Barney and Robin’s wedding. Season 8 left off at 10am on Friday morning, with the wedding scheduled for 6pm on Sunday out in the Hamptons. The entire season will comprise of the events of next three days (and probably a few flashbacks), which of course culminates in Ted meeting the mother. How will they fill up an entire season with one weekend? It may seem a bit strange, but everything has been leading up to this moment for show creators Carter Bays and Craig Thomas. I have no doubt they have been saving us the best for last.
