Tom decides to start by explaining a few elementary things: still water isn't usually clean, raw meat can cause food poisoning, campfires are critical and you need to sleep. Smoke rises, all rivers end, coldness can kill you. Although these are simple things, they become an incredible challenge to think of when you're hungry, lonely, desperate and afraid. He also teaches you how to light a fire with sticks, and how to move quietly. You quickly find out that using a bow and arrow is way out of your reach, as it requires a raw strength that being a coddled priestess quite simply doesn't give you.
