I think that the Jenny and her father storyline could've worked a lot better if she'd been given that storyline or another storyline other than the overdone rehash of her past relationship with Gibbs when she was first introduced on the show, but, now, she's been written too poorly and inconsistently and now a year and a half or so after she joined the show, I think it's really too little, too late to give her something to do, because, I've liked the episodes better when she is either in the background or hasn't been in the episode at all, because, it has seemed like the writers have had a hard time figuring out exactly what to do with her character without it looking awkward or forced. I think that if "Angel Of Death" had been a two part episode that maybe I would've been able to bear that episode and give it some points, but, since that's not the case, I can't. I think that once Jeanne finds out the truth about Tony that she will either be killed or leave him for good and given what we saw in this episode, I'm leaning more towards her being killed off now than her leaving Tony for good.
I watched and rewatched this episode and it had some good scenes, This episode wasn't a favorite of mine. I think that Tony at some point in the future will feel guility for lying to and worrying Ziva and I would be pretty surprised if his girlfriend doesn't end up hurt or dead, even though it is an undercover mission where he has to take precautions.
