I was there yesterday, and I can assure there was clearly something wrong, especially if we wanna compare the parade of last year.
I don't know if it is related to Locke and Croft, but the whole cast was detached. If you watch all the videos carefully, you'll see two groups of people, who were desperately trying to act normally.
The feeling was that some of them forced to do what they did when the camera was on them.
I don't think they love each other as they would like us to believe.
PS: Sebastian is definitely an extrovert person, but he's a seeker attention as well. That's not a bad thing, of course, but when I looked at him, it seemed he searched for the camera all the time. The camera that, I can assure, was always towards Kit Connor.
