In a new interview, the How I Met Your Mother leading ladies Cobie Smulders and Alyson Hannigan discuss their characters Robin and Lily. Beware of mild spoilers.

Speaking to USA Today, Alyson Hannigan discusses Lily’s pregnancy storyline this year:

In true sitcom form, it does not go as smooth as it should. I’m a little concerned about Lily’s pregnancy choices. She isn’t the most responsible pregnant lady.

Cobie Smulders previews what’s to come for Robin, saying:

Robin has had a rough year. There’s been a lot of mostly downs, so I feel like the ending (of the season) is a beginning.
