About six months after the victory at the Battle of the Tree of Souls, the Omaticaya clan had located and started to settle into their new hometree. A short while after this point in time, the clan has found its rhythm and the need for the clan leadership to constantly oversee the day to day activities of setting up house has lessened. Nobody in the tribe has noticed, but Neytiri has noticed that her mate has become a bit distracted from his duties as Olo'eyctan.
In their initial forming of the bond under the Tree of Voices, Neytiri had glimpsed the entirety of Jake's emotional and mental being. She had also noticed that were parts of him that were effectively hidden from the view granted by shahaylu. The Sky People were very good at telling non-truths and keeping their true intentions hidden from those around them. The reason for Jake's distraction was in one of these closed off parts of himself. It wasn't that Jake was lying to Neytiri, but it was that he was keeping something hidden that bothered her. Since Jake had started to become distracted, when she formed the bond with her mate, Neytiri made subtle attempts to discern what was bothering Jake. One time she caught a stray thought that was alien to her, but she was certain that it was related to Jake's change in behavior:
"...unfinished business..."
The next day she made a little trip out to the Tree of Souls to confer with an old teacher that taught her the concept behind the word: lie. If Grace Augustine could teach the meaning of this concept, then certainly she could offer some insight to why Jake was acting out of character and explain the semantics behind this phrase: unfinished business. In conferring with Grace's stored personae, Neytiri is able to gain a bit more understanding of how the Sky People's mind works.
Grace explains, "You see Neytiri, first you must remember that Jake was a marine. They are the toughest of the Sky People's warrior's. They are taught to rely on themselves first and foremost. Secondly, Jake went through an extended war on earth. Where the battle of the Tree of Souls lasted one day, the war in Venezuela lasted several years. You've seen the emotional scars that a battle can do to a person, imagine what a war can do to someone."
"So it is not strange that Jake keeps things to himself?", Neytiri asks.
Grace replied, "Heavens no! Jake is very well adjusted for a war veteran. Many other Sky People who went through the same thing had their lives changed to one of a living death. The things they had seen and been forced to do made them wish for the end to come."
Neytiri is comforted by Grace's memories/observations of Jake. Though there has been much pain in his past on his home planet and here on Pandora (as the sky people call it), she senses that Jake seeks no harm to himself. She also takes comfort from the fact that it is not abnormal for Jake to keep some things to himself. Though, it is a uncommon tendency between mates, Neytiri realizes that this will be something that she'll have to work on years with her mate to overcome.
For all his faults, Jake had first come to the people as an ignorant sky person. Remembering to herself, "Like a baby, making noise, don't know what to do." Her baby now, smiling with satisfaction. He had then went on to complete the training to become one of the people. Though he had been a spy for the Sky People, after witnessing their power at the Battle of the Tree of Souls, Neytiri had realized that Jake had not helped home tree fall. This was something that was destined to happen: Jake or no Jake. What harm he had done to the Omaticaya, he had made amends by marshalling the forces of the goddess and crushing the Sky People. He had removed an immediate threat to both her people and planet. He had also opened her heart to several things she thought she would never have again: hope, laughter and love. Neytiri sensed that Jake would be making a trip soon to complete this "...unfinished business..." or task left undone. Though, she knew he wanted to complete this task on his own, something told her that he would end up needing her help to see it completed.
