When Jonas is fleeing through various terrain and weather conditions at the end of the movie, his wardrobe changes a number of times and he is finally wearing a thick winter parka. All the while he never has a backpack or bag or anything with him and the baby when he initially flees on the motor bike. And where could he have even gotten a spare parka from anyway since the whole society was climate controlled to perpetual summer-like conditions?
When Jonas and the Giver walk home from their first meeting they pass by some people assembling a tree. From this point on the shot is flopped (Giver is to Jonas' right and the brake lever and swing arm of the front wheel fork of the bike are on the left side). The image stays mirrored until they they separate, when Jonas asks about the one before him.
Jonas: My name is Jonas. I don't have a last name. None of us did. That day, the day before graduation, I admit it: I was scared. Tomorrow we'll be assigned our jobs. Our purpose. It seemed everyone knew theirs already. Not me. I was lost. I always felt like I saw things differently. I saw things other people didn't. I never said anything. I didn't want to be different. Who would?
