Actually, I thought it was a good job of DeNouzo relentlessly searching for Ziva, dealing with the Mussad, and finally figuring out where she was, and finding her. She had been injured, sought help from an old female friend from childhood, who helped her, but as it turned out was engaged to Ziva's brother, and Ziva had to tell her she is the one who killed her brother. When DiNouzo & Ziva buried her box of memories, (she had not planned on going it the field she was in, and wanted time to herself, to rethink her life, and if something else was there for her) it was very touching. And where she told him he is loved.....and they kissed. A long and lingering kiss.
Later at the airport, the goodbye was really nice, and we saw DiNozo had now shaved, was on the plane back to NCIS.
