"How I Met Your Mother" is inching ever closer to revealing the "mother of all secrets." It could happen during tonight's Season 8 finale (the buildup to Robin and Barney's wedding!) as the below promo teases, or more likely, we'll have to wait until the ninth and final season of the long-running sitcom to meet Mrs. Mosby. But as Jason Segal (Marshall) put it in a behind-the-scenes cast interview, "It's gonna get weird if we don't meet the mother soon. We're gonna be, like, 60," adding, "This last episode really sets up the process of meeting the mother."
Neil Patrick Harris (Barney) is pretty confident that it will be a Season 9 reveal, saying, "My suspicion is that they're not even going to reveal the mother until the end of the series." Cobie Smulders (Robin) always imagined that it would happen in the series finale but is rethinking her stance: "I don't know; I think that it would be cool to have [the mother] integrated into the story more than that."
