Will it finally happen on the 100th episode of How I Met Your Mother? Will viewers finally meet the future mother of Ted's kids?

Whether or not her identity is revealed during that half-hour, producer Craig Thomas told Entertainment Weekly "it’ll be the closest Ted’s ever come to [discovering who she is]. He’s getting a step closer every episode this season, and episode 100 [we] kind of go bananas with it.”

Thomas won’t confirm that actually takes place, but did say he and fellow producer Carter Bays “are spending a lot of time trying to cast the female role in Ted’s story for episode 100.”

As for the installment's other major storyline, Neil Patrick Harris fans will be delighted.

“There will be a huge Barney story culminating in an enormous musical number that we’re going to spend way too much of Twentieth Television’s money on,” Thomas said. “Fans of Neil’s performance at the Emmys will enjoy the ending of the episode. It’s not a musical episode, but all of a sudden it becomes one. It’ll probably be one of the craziest things we’ve ever done on the show.”

That's saying a lot!
