The last two episodes of How I Met Your Mother's eighth season may be titled "Something Old" (airing May 6 and featuring the return of Robin's dad, played by Ray Wise) and "Something New" (May 13), but don't assume that means we'll finally see the long-anticipated nuptials of Barney (Neil Patrick Harris) and Robin (Cobie Smulders). "I don't want to necessarily promise the wedding," executive producer Carter Bays says. "It's more complex than that."
What Bays does promise is a "fantastic bachelor party" for Barney on the April 29 episode of the CBS comedy and "some earth-shaking events in the finale, including some new tidbits about the mother."
The finale takes place during the week leading up to the scheduled wedding: Barney and Robin connect in a sweet way; Marshall takes his first trip with baby Marvin to see Grandma in Minnesota; Lily gets offered a new job; and Ted makes a big decision that "will end the series as we know it," Bays says. "We're going to be taking some surprising risks with time. The finale is almost like a pilot for the new series that the ninth [and final] season becomes."
