Look at these 2 pics below: Do you notice anything wrong? I do. In the first pic, all the Autobot survivors are coming from one side of the city, but on the second pic, Bumblebee and Ratchet seem to have come from the other side of the city, and that puts them on the other side of the bridge. So how can Bumblebee and Ratchet be on 2 different places at the same time? Unless they crossed the bridge, but I don't remember that happening. So Bumblebee and Ratchet are on the side of the bridge where Megatron is dead on the ground, but they came from the side of the bridge where Sentinel is dead on the ground along with the rest of the Autobots. You can also notice the buildings in the background of each pic are different, so that makes it clear that Bumblebee and Ratchet are on 2 different places. Or maybe Optimus never turns around, and the editors put Sentinel where Megatron was and changed the buildings in the background, which I highly doubt. I'm taking all this from 2 screen shots, but it's been long since I last watched the movie, so I could be wrong about all this. But still, if Bumblebee and Ratchet never cross the bridge, how can they be in 2 different places at the same time?
