Perhaps the longest story anyone has ever told about meeting their significant other continues this year with the sixth season of How I Met Your Mother. The show is about as far as I'll delve into the laugh track sitcom stylings of network television (simply because Neil Patrick Harris and Jason Siegel are just so damn great on it), but now it looks like the show may finally be moving towards the meat of the story that the series' title promises. EW has learned that Jennifer Morrison (House M.D.) will be joining this coming season of the show for an extended story arc and it's quite the big deal.

Executive producer Craig Thomas says her character is "“the biggest female character we’ve maybe ever added to the show in Ted’s life." He goes on to say, "This is a big arc—a huge arc. It’s going to be a little less date-of-the-week for Ted, which season 5 was. This is going to be a big saga for Ted. [It's] going to be a big over-arching story that will take Ted on a journey that we’re really excited about.” So who exactly will Morison be playing? She's a rabble-rousing activist who’s hell-bent on saving the Arcadian, an old New York hotel that’s scheduled to be torn down to make way for the Goliath National Bank tower—which Ted just so happens to be designing. That's certainly a love story worth telling the kids about. We'll see what happens when the new season kicks off on September 20th.
