Nazanin Boniadi on her 'How I Met Your Mother' return and who Barney belongs with


We last saw Nora ( Nazanin Boniadi) entertaining her parents while Barney ( Neil Patrick Harris) looked on, as sad as we've ever seen him, from the sidewalk.

The once (and future?) love interest makes her return to "How I Met Your Mother" during the season finale, "Challenge Accepted," and Zap2it met up with the actress just after filming her first scene back.

"They don't tell me anything until the next episode that I'm up for," she says. "It's all a big surprise and mystery for me, but I'm loving the journey."

We'll have a better idea of how much farther that journey may take her after the finale -- but we can say that when Barney runs into her on the street, the surprise seems to be pleasant for both parties.

But Nora does present a big obstacle for one of the biggest goals in all of "HIMYM" fandom: a re-coupled Barney and Robin ( Cobie Smulders). So we asked Boniadi what she thought about being the other woman.

"I'm a fan of both of those characters," she says, "and the actors who play those characters, so it's tough for me to say... I don't think its about him being with either one. I think it's about him evolving."
