NCIS - The next day.
Ziva is reading her mail.
How does it feel Officer David to be working with the man who killed your brother? Being around him day in, day out and taking orders from him. How does that make you feel? Why did he have to kill him anyway? Surely he could have arrested him? What are the courts for? Who anointed Gibbs judge, jury and executioner? You are a Judas Officer David. Gibbs may have pulled the trigger but you betrayed Ari. His blood is on your hands.
How ridiculous she thinks. Who sent this? I know what Gibbs did and why he did it.
"Ziva?"
I need to tell Gibbs about this.
"ZIVA?"
"Yes, Tony."
"We need to head out to do that interview now."
"O.K."
"Are you alright? You seem a little preoccupied."
"I'm just plummy Tony" she responds picking up her gear.
"Peachy. It's.." oh why bother DiNozzo thinks as they head to the elevator. He doesn't believe her denial but is willing to let it rest; for now.
Later that day when they are alone Ziva shows the letter to Gibbs. "I think someone may be coming after you Boss."
"With a piece of paper Ziva? I faced worse in Kuwait."
They both smile.
Author's Note - I do know it was really Ziva that killed Ari not Gibbs but remember he took the blame to protect her from her father. I don't know if this secret has been exposed post Season Four.
