Jack Dunne is a veteran who returned from Vietnam only to get locked up in a mental ward due to his memory loss and post-traumatic stress. But he finally escaped, he felt better now.
In the bus station, you both were fighting for the same ticket! It was crazy but...he was a gentleman. In his own way- he bribed the ticket man to get an extra seat. He gave you the seat and he would sit on the floor and sit with others.
But both of you didnt really know where to go. Several bus rides later and you two seemed to be connected. But then the bus broke down. Well... Jack seemed to like you quite a bit. He was always trying to put a smile on your face and trying to be social with you.
On one night, he had been sitting a seat away from you, he was asleep. But you could hear him quietly whimpering. It was sure that he was having a nightmare, possibly connected to the war.
