They find a cave to hide from the rain. They notice that everyone is shivering and that Ash is starting to get a little hungry. Dawn remarks that if they even get to their destination on time, they'll be all cold, hungry and miserable. Unfortunately, the cave they're in doesn't have electricity and they don't have matches so they can't really start a fire that way. Ash then remembers that Brock packed them some food, he pulls out a can of soup, which unfortunately can't exactly be enjoyed at the moment. Perhaps there is a way they can fix all these problems. Ash contacts Siara and she explains to them about energy and how it can be used.
