I'm vulnerable in this environment...all alone. I decide to put traps on the entrances. It's a tripwire that releases tons of apples. Then I can act on it. I found a rusty sword, which I decided to sharpen should anyone try to invade.
I wake up, from lying on the ground in the forest. I change clothes, and see the others at a campfire. "What happened while I was gone?" I ask, figuring everyone knew my secret by now.
