"How I Met Your Mother" Season 9, Episode 1, "The Locket" begins the series ending of the hit CBS sitcom. This ninth and final season marks the end of an era for HIMYM fans. But for Cristin Milioti and Lady Tedwina Slowsby, things have only just begun.

How I Met Your Mother Season 9, Episode 1: What happens to Robin's locket?

Spoiler Alert: This review contains spoilers for those who have not seen HIMYM Season 9 premiere. Read at your own risk.

Ted Mosby (Josh Radnor), Marshall Eriksen (Jason Segel), Barney Stinson (Neil Patrick Harris), Robin Scherbatsky (Cobie Smulders) and Lily Aldrin (Alyson Hannigan) return for How I Met Your Mother Season 9. They are officially joined by Cristin Milioti, who plays the titular "future mother" role. And she has one powerful line -- 3 words -- in the premiere episode: "Here I am."

After Ted's dramatic realization that he has in his possession Robin's "something old," it's revealed in the premiere that he may have lost it forever. Interestingly, and because there's no coincidence in the HIMYM universe, Robin's locket was "affected" by Ted's decision to move in with Stella (Sarah Chalke) a couple of years back.

Ted Mosby and the Future Mother Chemistry: Oh, Tedwina!

"Here I am," after all those years. In a flash forward, viewers see Ted recalling to the mother how he feels about the "love in (her) eyes" and "baked goods in (her) undergarments." The mother is also heard calling Ted, "Lady Tedwina Slowsby." Sounds weird, yes. But when two dorky individuals make a cute couple, weird things tend to get said. That says a lot about the wonderfully adorkable chemistry between Ted Mosby and the mother.

The sweet moment between Ted and the mother gives less hope for many Ted and Robin shippers. Cobie Smulders, for her part, has said Robin simply doesn't love Ted the way she loves Barney.

As for a theory that the mother eventually dies (judging from the "The Time Travelers" episode), many fans are keeping their fingers crossed. Curiously, there is a "How Your Mother Met Me" (instead of a "How I Met Your Father") storyline coming up in this HIMYM final season.

How I Met Your Mother Season 9 Brings Back the Favourite Guests

James Stinson (Wayne Brady) returns! Barney's brother, a favourite recurring guest, has announced he's getting divorced. It affected Robin and Barney, but the two have later shown a firm resolve.

Wayne Brady is only one among several "best" guest stars expected to return in the farewell season of How I Met Your Mother.

Meanwhile, Lily still doesn't know about the shift in Marshall's career ground.

There were doubts raised on How I Met Your Mother Season 9's wedding weekend season. But as far as "The Locket" and "Coming Back" are concerned, the flashbacks and flash forwards are working smoothly. Twenty-two more episodes left! Check out the slideshow for some fandom posts on Tumblr.
