You hide, you know that you have to as you are the last member of your tribe. If you don't hide, you might get hunted for some sort of resource or some other reason, but it kind of sucks not being able to make friends.. it gets quite lonely sometimes.

Then, you hear / see (or feel depending on your tribe) dragons approaching, it would be violating the rules if you show yourself.. but.. they look trustworthy? well maybe not the seawing... but.. should you show yourself?
