Remember shia was talking on Jimmy Kimmel about how there was this scene where michael and him kinda got into an argument about which song to pick? and shia explaned, "in the scene my friend just died... and we had to pick a song because i get emotional in the scene" or something like that... There were also rumors that michael walked off set because of it, which he later addressed. However, shia said did in fact say they got into a little argument about what song to pick for the scenes. So, maybe they did recognize Ironhide's death in a deleted scene? cause shia said in the scene he was sitting there and thinking about the loss of his friend which happened right in front of him? does anyone know what im talking about?
