Research (NCIS)
The first Thanksgiving is pretty disastrous, which is a surprise to nobody since Senior had been cooking dinner and by 10 p.m. every man in the house over 50 was drunk as hell, and Tony had ended up tucking them into bed together in a move motivated primarily by a combination of childish irritation and physical inability to move Senior to the guest room. Christmas is weird, since it'd had been less than a month later and by then Gibbs has kissed him, twice: once by the coffee stand to the general horror of everybody at the Navy Yard, and then once at the grocery store, saying, "Come home with me, give me a reason to get a Christmas tree," and what the hell does anybody say to that other than, "Okay," and "Let me grab some milk, first."
Tony's great at the first three months of a relationship. He's fun and sexually adventurous and all of his weirdness still comes off as charming. It's month four that usually fucks him over. He's pretty resigned to it, as a rule, but this is Gibbs, who Tony has wanted to marry since he still thought he was marrying a woman in Baltimore, so obviously it's going to take a lot more effort and also some research.
He cooks, he cleans. He surveys the happily married guys in the bullpen (there are four; there are about 75 divorced guys, not including multiple divorces). He freaks out, a lot, and lets Gibbs choose what TV they watch (Tony has never hated Hitler or the History Channel more in his entire fucking life). He tries to be entirely accommodating in bed -- which is how he ends up throwing out his back, and confessing like a common criminal under Gibbs's glare and the seducing influence of percocet 12 hours later.
