Robin’s surprising development caught fans by surprise, and now Craig Thomas has spoken out about the writers’ decision, as well as loads of things happening in the second half of season 7. Beware of spoilers.

In the TV Guide interview, Thomas warns that we will need Kleenex tonight, and that a lot of unexpected things will happen. He says,

I think it’s fair to say that the episode is different than anyone had imagined coming into it. It’s one of those where while we’re shooting it and editing it that you see people tearing up. It’s very funny, but it’s very emotional too. The very end of the episode seems like it’s made a lot of people cry, but it’s a good cry.

What does this mean? While Thomas says this episode puts Robin at a crossroads, they won’t be exploring whether or not Robin will decide to keep the baby:

All I can say is she gets this huge piece of news and there are more revelations in the episode that are definitely things that she would want to talk about with a friend, but she just can’t quite bring herself to. […] In many ways, I view this season as a Robin season. We’re going to remember as a series how important she is and that there’s a reason [Ted is] telling this story.

To us it really sounds like Robin won’t, for whatever reason, end up having a baby. On Barney’s reaction, Thomas says:

He’s trying to deal with this huge information he’s got between him and Robin and how he moves forward from it. We’ll meet [Becki Newton’s] character a little bit later. She will be a serious love interest for Barney and she’s going to be around for a while. … It’s going to be very different from his relationship with NorIt’s a little Frasier Crane and Lilith Sternin — two people who’ve met their match. He needs to lock horns with somebody to get his mind off what’s happening.

There is much more to this interview, including what’s coming for Lily, Marhsall and Ted. You can read it all here at TV Line.
