Things broken*throws over shoulder... BANG!!!*
Anyways from what I got I think Nomen is suitcaseman and he's looking to join the tribe for one of two reasons:
1.Running away form past wrong doings, to him or by him
2.Looking for something to help his stutter or self-a-steam issues
He walked into the head tent or building or what-ever and saw le interesting woman.
And a few other theorys, but most of them involve quantum physics.
