Hmmm... I don't know but,it seemed as if seeing Ziva jealous of Jeanne was more heartbreaking than Tony being jealous of Rivkin.
Not saying that it's never heartbreaking seeing half of the Tiva tandem with someone else....it's just that, IT'S ZIVA...and it's like the world was being unfair to her because all she wanted was Tony but he's the only person SHE WANTED SO BAD yet she couldn't have.
Same goes to Tony...He wants Ziva so bad...but when he's the one who gets jealous, It's a different story. You know what I mean.
I wanna hear your thoughts.:)
