6) who forgets their anniversary?
I think people expect it to be Gibbs, but you know what? I’d go with Jack. He forgot Valentine’s Day on the show because he has no need to remember it. But an anniversary? In one of my Married!Slibbs fics, I have Ellie chastising him for not remembering Jack’s birthday (only to find she was wrong and he was just planning a surprise) and telling him he had to remember those kinds of dates. Birthdays, anniversaries, etc. Then I had him rattling off exactly how many days to go before their anniversary. I genuinely believe he would be that kind of man, because, despite him trying 4 times, I do think he respects the traditions behind marriage. He’s just not good at the specifics.
19) who clings to the other for comfort when they’re sad or scared?
I don’t know how often we’ve had the chance to see Gibbs in a situation where there’s an opportunity for him to find physical comfort in someone else in either of those scenarios. So it’s probably predictable to say, it would be Jack. She IS the more demonstrative of the two, though she keeps things very tightly to her chest, too. I would prefer the question to be, Who goes to who for comfort? because then, it doesn’t read so trope-y. And in that scenario, it would actually be Gibbs. We’ve seen it on the show already, multiple times, in his own quiet way.
Have I done the entire list yet? :)
