Has anyone seen the shorter version (10-15 seconds) of the Hub Promo for the second part of Season 2? I have only seen it in the little box that appears while credits are rolling - never full screen. It happens fast when I'm not recording. There seems to be a scene that is not in the longer version. It has an Autobot or Decepticon foot stepping on a stone. Is this from an episode that has already aired? If so which one? I know its trivial, but I'm curious.
