Spoilers ahead, so watch the episode before you proceed. Especially this one, because you know they like to do all these big reveals at the end of the season. Why do you think they stretch these things out so long? I mean, the entire show is built around the final reveal when Ted meets "The Mother," and if you've been watching for a long time, you don't want to go and get spoiled right when they finally get to the good stuff. And even if that's not the big reveal, you know we're going to find out who Barney is marrying. They've been teasing us for a whole year about that, so don't you think you should just watch the episode first? That's what I thought. I can't believe we even have to have this conversation.
