That is why, when speculating about any “Ducky tribute” episode (no official plans have been announced, yet), there have been cries of, “Well, Mark Harmon/Gibbs has
to be there!”
“Yes! And Michael Weatherly/DiNozzo!”
“Ooh, a perfect time for a #Tiva reunion, if Cote de Pablo comes back…”
“But don’t forget Emily Wickersham! We need closure on Bishop’s exit!”
“Can we also get visits from some ghosts of dead characters, too??”
Yeah, you can see how this can get very out of hand.
The fact is that — any scheduling/availability issues aside — you can’t simply “bring back” Gibbs. Or DiNozzo. Or any of the above. No matter how much their presence might be warranted for this occasion.
I mean, you can absolutely bring back Gibbs — especially if Mark Harmon knows about it. But then you’ll have to commit some dialogue/screen time to coaxing updates out of the team’s taciturn former leader.
Ditto Weatherly/Tony and de Pablo/Ziva, who have not shared a scene together in more than a decade (but presumably reunited off-screen after de Pablo’s most recent solo visit). An appearance by Tali’s father or both her parents will consume much storytelling oxygen, since fans of that primetime supercouple will want/need to know how their unconventional family unit is faring.
And if Emily Bishop resurfaces after abruptly peace-ing out on NCIS — including Nick, her apparent boyfriend…? There will be those demanding some i’s be dotted and t’s get crossed on that front.
What that all adds up to is, if you accommodate even two of the aforementioned returns, suddenly this Very Special Episode is a lot less about David McCallum and Ducky, and more about “Boss, what kind of fish are you catching in Alaska?” and “Sooo, might Tali get a big brother or sister anytime soon?”
Is that a trade-off you’re willing to make, all in the name of a well-attended trip down memory lane?
Or do you see some other option that brings back many of the above but successfully “cheats” us on proper catch-ups?
Me, I could be content with a Case of the Week that thoroughly vexes Dr. Palmer as he mourns a recently passed Dr. Mallard. But it’s flashbacks of wisdom imparted over the years, by Ducky, that helps Jimmy near single-handedly crack the case, ahead of a proper memorial for his mentor.
