When he went jogging that morning, Nathan ran into his neighbor, Cheyenne Fox. Cheyenne has been a friend of the Wassem family since he was a teenager. Nathan was actually very attracted to her, but never tried anything, since she's older than him to begin with, happily married with children, and clearly not interested in him. Of course, that doesn't mean he doesn't still like her. 

(By the way, At the time this picture was taken, Cheyenne had lost her original hair, I guess it was due to some makeover done by me that went wrong, oh well.)

Since Cheyenne is married and Nathan has a girlfriend, the talk they had was about family. Nathan filled Cheyenne in on the latest developments, that he and Kristina had left her parents' home, and that Kristina had a boyfriend she had met in Shang Simla. Cheyenne nodded and said very little, she probably thinks Nathan and his sister are still just kids.
