Death in the mountains

I was pretty tied, i knew it will not take long for me to get asleep. But before I closed my eyes, I did set up alarm to wake me up each half an hour starting in an hour. I really was curious. If somebody takes the food, who is this, total stranger or one of us playing games.
First two times alarm rang I didn't even hear it. Third time I woke up and put my face out of tent. There was nothing interesting and nobody outside. Forth time I did see him.
