Ok, I totally buy why Simmons is in a wheelchair. A Decepticon threw him out of the back of a moving car. What I don't get is what happened to Dutch. He stops the car in front of the knocked down sign with no damage done to him. Later he shows up with Simmons in a neck brace. Then when he is on the computer during the Chicago fight, he doesn't have a neck brace. Why did he need a neckbrace and where did it go?
