How I Met Your Mother producers Carter Bays and Craig Thomas joined stars Jason Segal and Alyson Hannigan at the Friday TCA panel, offering up some scoop on Ted’s upcoming storylines, Marshall and Lily’s pregnancy, and casting the mother!

EW reports that Ted will do some “soul-searching” in February.

We’re going to see Ted do exactly the assessment [that] “Boy, I’m years… past the moment that Marshall and Lily got engaged, and I’m still sort of out here looking.” And he’s going to come up with what he thinks is the answer, and then we’re going to kind of explore whether it is the right answer for him.

Bays said that they still haven’t figured out the most important piece of the show—casting the mother.

There is the one school of thought where you want her to turn around and she’s Jennifer Aniston because it has to be, like, a huge star, but maybe it should be someone we’ve never seen before.

He also talks about Marshall and Lily’s life out in the suburbs, saying that viewers will soon learn how they plan to keep everyone together in the bar with Lily’s pregnancy:

It’s a real identity crisis when there’s a baby on the way, and I think we’re going to kind of explore that. And I think moving to the suburbs was part of that for Marshall and Lily, sort of them falling into this role that seems like what you have to do when you have a baby on the way. And it’s partly true but I think they’ll find some happy medium.

Thomas also added some details about Marshall and Lily:

We’re definitely going to explore them realizing that it is a little bit isolating to be out in the suburbs, away from all their friends and the bar, and we’re going to see them deal with that in actually the next few episodes that will air. And I think we can say that it’s not necessarily a permanent stop, and there will be some fun, arc-y stuff with these two about that.

The episode that airs this coming Monday is all about how much sort of the two halves of the group now miss each other once they’ve moved out of there, so we pick right up on that.

Do you think they should cast a major star or an unknown for the role of the mother?
