I admit, I freaked out last Monday and Tuesday but the more I thought about it, the more I got to thinking they're playing with us. If you were a show runner and there was a persistent fan theory going around for some time, wouldn't you play with the audience just a bit? I would. Plus the last episode's title was "Vesuvius." There's really no good reason for this episode name. Why name it after a volcano? Wouldn't you say that the fans blew their tops after that one? It was the reaction they were going for. I mean, what else? Ted didn't get mad about the movie. Robin didn't get upset like Lily wanted her to. Barney was freaking out a bit but he didn't explode. The entire gang took Ted's leaving really well. Future Ted's reaction was more of a whimper than a bang. People have made the argument that it's saying that it's a moment trapped in time like Pompeii. Okay, I can get behind that. Maybe. But again, going back to the second episode of the season. Ted showboating on the crossword. "Vesuvius! No, that doesn't fit." I really think this episode title is breaking the 4th wall because the creators KNEW putting this point in was going to make us blow our lids. And it worked.
