Thanks to dollsome for the article -- 'How I Met Your Mother's' Craig Thomas on Ted & Barney's Breakup, Eriksen Babies and The Future of Robarn'
Highlights (vaguely spoilery) :
...the last few have been a lot of fun. Especially the Robin-Barney (or Robarn, as I like to call them) stuff. Last Fall when I was on your set, I mentioned the possibility of this pairing and everyone got a little quiet, so I assume it's been part of the master plan for awhile?
[Laughs] Yeah. I think both us and fans of the show saw that they had great chemistry back in season one when Barney and Robin kind of wingman'ed each other one night in "Zip Zip Zip" -- they played laser tag and smoked cigars and stuff and all the fans started speculating that clearly it has to go that way. We just didn’t want to rush towards it, so we held off for a while. But ultimately we knew we wanted to get to that because they’re great together and we thought we’d get a lot of funny and interesting stuff out of it. It’s probably one of the best parts of our back nine [episodes].
Did the strike sort of speed this storyline up, because you wanted to do something cool when you came back?
It definitely did. In the middle of the strike, we didn’t know what we were looking at. We didn’t know how many episodes, if any, would [be ordered]. So we had to sort of think, what’s the best thing we could give the fans? If all we get is three episodes in May sweeps, what would be the most exciting thing to write? And we realized it was the Barney and Robin stuff.
Now that you’ve seen Robarn together -- as in, in bed together -- how do you feel about the pairing? Is there more to come?
People will see in the finale that there’s definitely a hint of more to come. We love the two of them in teams together, we love the complication we’ve now added into their friendship. Most of the focus has been on patching up the relationship between Barney and Ted, but at some point we’re going to see that [Robin and Barney's] experience has [other] repercussions and is definitely going to mean something moving forward.
Why is Ted so angry with Barney but totally cool with Robin?
[Laughs] It’s funny, everyone has a different opinion on this -- everyone in the writers room, different executives, my wife -- they all have a different idea of how they’d feel about this situation, which is what makes it ripe to explore. Our feeling, from a writing perspective and even from a viewer perspective, was that we’ve seen a lot of Ted and Robin angst already. Even this year, in one of our better episodes, "Slapsgiving," we saw Robin dating a new guy and Ted and Robin have a relapse and question their friendship, can they even be friends? Ultimately they work it out and realize they are friends, they have the same sense of humor and they want to keep being friends. We didn’t want to rip that asunder again. In terms of whether that’s realistic or not, there seems to be some debate. But in that episode, "The Goat," we see Robin apologize to Ted [for sleeping with Barney]. She comes forward and she’s honest in a way that Barney wasn’t. We thought that earned her a lot of points. And we also did a scene in the very next episode where Ted says that it wasn’t just about the fact that Robin and Barney hooked up. It was about him and Barney, something deeper in their friendship. He's trying to move forward, he's dating a single mom, he's trying to grow up and Barney’s still busy being legendary every night.
... People will enjoy the finale in terms of the Barney and Ted and the Barney and Robin stuff. That’s the main focus and a lot of events shift around in their lives quite a bit.
Oh, show, I'm so proud to say I never doubted you. :D
