Not so normal case

G Callen as well as Eric Beale grew up in the foster system. One time they were in the same children's home as well as the foster home afterwards. With them however was a small girl, Izabel or Iz as they called her. Both the boys immediately felt really protective of her since she was the smallest and youngest kid there. They were always protecting her from the head of the children's home, who has taken a special liking towards her. They made sure she did get something to eat and was alright. One family had taken the three of them, the happiness however didn't lasted long since they were getting abused by their drunk foster dad whenever his wife left.
They ran away, stayed on the streets for nearly 3 years together before another social worker saw them and placed them in another child's home. They got separate, however they managed to stay in contact and helped each other out.

Now they all are grown up. Callen with Eric along works for the NCIS, even thought no one knows how deeply connected they are. Iz was in the NAVY as well, but then decided to leave to open a bakery.

So what will happen when their next case is about Iz? Callen's fiancé and Eric's „little sister"? Will they tell their team about whats going on?
