Less than a week's time will see CBS favorite 'How I Met Your Mother' return for an hour-long ninth and final season premiere with "The Locket / Coming Back," kicking off the final time-turning tales of Ted Mosby and his bride-to-be. We've seen a few looks at "The Locket," but check out what stars new and alike are returning in the first photos from "Coming Back"!

In addition to the return of Wayne Brady as Barney's half-brother James Stinson (perhaps the source of a very peculiar cake seen in the photos), the new shots from "Coming Back" feature our first still looks at Cristin Milioti as the still-unnamed mother, whom we know to meet everyone but Ted before the end. Spoilers be warned, from CBS' official description of the September 23 premiere second-half "Coming Back":
