'How I Met Your Mother' will begin the final leg of its 9-season journey next Monday with hour-long premiere "The Locket / Coming Back," but that isn't stopping CBS from sharing the goods in advance of the long wedding weekend. Four new sneak peeks of the final season premiere have emerged, featuring a new friend for Marshall, a shocking revelation for Robin and Barney, and yes, another glimpse of the mother!

The first new clip from Monday's all new "Coming Back" sees Lily driven to abandon Ted for his nerdy road trip trivia, something we know to put her in the path of the mother herself on a train to Farhampton! Meanwhile, Marshall frets to an airplane passenger (Sherri Shepherd) about his mother potentially spilling the beans about his potential judgeship, while Barney and Robin find they have a surprising family history in common on their way to the wedding.

Elsewhere, the final season of ‘How I Met Your Mother’ has recruited such guest stars as returning 'Karate Kid' star William Zabka, ‘True Blood‘ star Anna Camp (replacing ‘The Office”s Ellie Kemper), ‘Revenge‘ star Roger Bart, and Wayne Brady and John Lithgow reprising their roles as Barney’s half-brother James and biological father Jerry. In addition to clarifying the final season’s wedding weekend format and releasing new promos, clips and photos, CBS previously revealed that all four regulars would meet the mother prior to Ted.

You can get an early taste of the final 'How I Met Your Mother' season premiere in the clips above and below, and tell us in the comments what you want to see from the nine-seasons-in-the-making meeting!
