I like the one with Carly and Dylan. And the last one I have no idea what's supposed to be happening.
I think thats Spoiler the room described as "the egg" in the novel. Its where Simmons, Mearing and Dutch work to help the autobots and co fighting in Chicago.
Actually I think Spoiler that scene takes place during Sentinel Prime's resurrection, judging by the look on Director Mearing's face, which seems to be shock or surprise.
This. But thanks for posting these nonetheless. Does anyone know what Sam and the NEST soldiers are sliding off in the third image? Is it the glass on a skyscraper? *shudders* That's actually one of my worst fears!
