That episode left me feeling sad and mind-blown at the same time. I didn't think the writers would give it away so easy, however, so I was skeptical of Robin's narration since the beginning.
The identity of Barney's bride is still high in the air, as far as I'm concerned, no matter how much I may want her to be Robin, and how much logic would dictate that it is Robin. But it stands to reason, based on an earlier interview with the producers, that Barney will meet another woman this season.
