When Director Miriam was asking if Optimus was giving her the silent treatment, Ironhide replied that they have seen that before. I've got to wonder the hows and whys and such about that. Was the former Director Galloway so upset with NEST for ditching him off the plane that he merely stared at everyone behind it? Maybe the Autobots blew up the wrong target and knocked off some allies by mistake. What do you guys think would cause someone to (and very comically at that) give the Autobots the silent treatment?
