These are my predictions what will happen to Brian. First of all Brian will explore some new things like caves dungeons etc. Then he will learn something new to do. He also might get in even more trouble than he was in before. He will go back to the plane to get some resources, but the problem is that plane is at the bottom of the lake and he might have trouble getting drowned because  Brian might run out of breath before he gets resources and comes back up. Also some resources might be not useful because they were under water for a long time. He will also make some big fore signs to increase chances of him getting rescued faster. Then when he gets rescued he will become famous and rich, he will also probably make a lot of interviews how he survived in the Canadian woods for a long time. Someone will also probably write a book how he survived in Canadian woods for a long time. When he gets rescued he will first be sent to a hospital then they will send him home to his dad’s house and dad will make him a nice dinner. That was my prediction what will happen to Brian soon.
