Ziva's new "Quirk"! What are your thoughts?

I really don't think she knows she's doing it. I think she does it when she's nervous, even though when she does, she doesn't seem like she is.

I think it's もっと見る of a subconscious thing that she doesn't even realises that she is doing, a bit of a habit that she gets every time in those situations and it seems a bit flirty when she does it. I don't know about others and I may be wrong but from experience - I usually do those things in situations around guys that I'm into. ;)

I do something similar as a nervous または even boredem thing. Perhaps, it's what she does when she's comfronted with something sexual after the allued to sexaul assult in Somalia, it would be normal for her to be 'fearful' または 'nervous' about sexual things.

Either Cote de Pablo's managed to stop herself fidiling on camera, または its a set up によって the cast as a nervous habit.

And with her ears, only season seven did Cote start wearing earrings, maybe she's not used to them yet.
Hey, its just a thought.
