Surveillance Video

O.k.-so in the roller rink surveillance video there is a point when the camera pans past Damien and Domini and a group of kids kinda in the background-Damien looks kind of angry at being taped and it almost looks like him and Domini are arguing up to that point-Her back is to the camera but she is in kind of a defensive position-Also there are other's around them-All these kids who said they were "just friends" or didn't know Damien well are around him-so like there is this jovial atmosphere in this roller rink with all these kids having fun but then when the camera pans by that group they all seem uncomfortable and out of sorts-just something I noticed-maybe it's nothing but I was just wondering if anyone else noticed?
