I think Brian is going to burn a small chunk of the forest to attract attention to the plane. The plane will come and try to put out the fire and see Brian. When the tornado devastated and destroyed Brian’s habitat it also made the plane closer to the shore. I think Brian is going to go inside the plane and try to contact the police or someone to come save him. Brian is going to use the radio to contact someone. I also think when the helicopter comes they will see the plane in the empty lake to pick up Brian. If this doesn’t work he will just stay there until help comes.
