Ziva sat on a bench in the city, checking things on her map and drinking a cup of coffee. She'd spent the last few days...and nights... dealing with the effects of the fog and trying to figure out exactly what it was. To get away from it, she actually went out of the domes and to the church, spending the night there...it had at least helped clear her head.

She'd come back to the city after the fog burned off. At least she had narrowed down that part... but she didn't know how to stop it from happening, except by leaving the city before it started coming in at night. Sighing and taking another drink of her coffee, she focused again on the journal, reading entries on it to try to see what other people knew.

What would Gibbs do in a situation like this one...?"
