Wow. I don't think I've laughed as much as I did watching the new episode.
I don't know if they intend to use the ex-wife more on the show, if Vance's suggestion was taken seriously, but I agree with Skippy that Fornell needs to be more active. The one thing I like most about him is he makes Gibbs human. Gibbs acts like a person, with a friend, when he's around. The problem is though, is that Diane can't be in ever episode, so you can't have those kinds of laughs all the time. I think it makes sense to use her more sparingly, but Fornell could be a good fit. Director though? No. Not gonna happen. Plus I think I've said before that Vance probably isn't going away for a while.
Did anyone else catch the reference to an older episode? Abby says something about they don't have a national directory of fish, or something like that. I think she was referring to one episode where they actually use the directory of turkey DNA (which exists in real life) to help solve the case.
