It did feel a lot like filler, but I guess after the stellar season this show has had, an episode like this was bound to happen. It was enjoyable, I was hoping we'd get some more buildup to whatever is going to happen with Barney/Robin, but I actually thought that the Tony/Stella stuff was kind of interesting and it forced Ted to confront his own immaturity and shortcomings and admit that he wanted to find "the one". It's amazing that it's taken him several seasons to come full circle to where he was in the pilot, but it was also a nice wrap up of his relationship with Stella. I seriously cannot wait for next Monday, I have a feeling this episode is going to be epic, although I've yet to read a single spoiler about what's going to happen. I'm just going on a gut feeling lol.
