Dave Vasquez was an animator at EA from mid 2003 – early 2009. The screen shot below is of a short 8-sec video titled, “Just For Fun”. With the theory that Generations was a filler EP/a way for EA to make more $$$ by removing stuff from the Base Game, it might be possible that the Imaginary friend might have been planned for the base game. That’s just my opinion. Anyways, once you see the video, you’ll instantly recognize the walk.
