Here is some thing that confuses me with this one scene. First. Why did Sentinel want to kill Ironhide when clearly he could have killed either bumblebee or the other bots. Second. Nobody and I mean nobody did any form of effort whatsoever to save Ironhide. Last and not least. Thay never mention, nor talk about it again whatsoever. A little mourning scene and a speech from Optimus could have helped. Sorry, but no, we had to watch this one scene with Sam and his parents from hell.
