Wild theory: Jenny Shepard is taking/viewing the pictures while in a wig because she has the hots for Tony and wants to be his girlfriend.
Yeah, that's far-fetched, but I am really wanting them to wrap up this little teaser mystery. It's getting on my nerves, much like the miniature killer on CSI.
One little detail I liked on this week's show as Ziva showing up wearing the bright orange knit hat the dead-from-radiation guy wore when he ran. I thought that little detail, as small as it was, round out her character a bit.
