the show never gave us a high school reunion episode which is a staple of procedurals/crime dramas so I came up with one, that's why the dialogue is in script format(ish)
the body of danny's high school guidance councillor is discovered on the school grounds, all ties lead to a huge pool of potential suspects including former students and teachers and maybe even a janitor with mob ties. too many suspects with skeletons in their closets are likely to lie to the police and the case could easily go unsolved.
luckily, danny's 20 year reunion is coming up, so he is asked by the local pd to go undercover and secretly question his classmates because they are more likely to spill the secrets if they don't know they are being investigated, as people love to gossip at this kind of events.
danny initially didn't want to go to the reunion which bummed steve out because he was hoping to tag along and get some of the high school experience he had missed out on, and maybe find out some more about danny's life before they met.
steve: i don't get why you hate the idea so much.
danny: i know my wicked good looks and charming personality may lead you to believe i was popular in high school, but that was not the case. of course, you wouldn't get it, i bet you had girls fighting to the death for the pleasure of going to prom with you.
steve: *looks down* we didn't have one at the academy.
danny: right, sorry, forgot you came off the conveyor belt at the factory fully formed. most of us regular flesh and blood humans don't wish to revisit the awkward teenage years. but that's a moot point right now, i gotta help my buddie at the newark pd.
and so steve ends up tagging along. for back-up, of course.
(picture steve and danny standing in the ballroom at the reunion as danny explains to him the veritable who and who of his former classmates/suspects)
former prom queen: so where is the lovely mrs. williams?
danny: *looks at steve across the room talking to some people* he's over there. i let him keep his own name, because i'm nice like that. babe?? come over here, don't make me look like a loser who came to his high school reunion by himself.
of course, steve plays along, even tho initially danny rejected the idea of posing as a couple but he understands that being divorced already makes danny feel like a failure on his own, he doesn't want to give the former mean girls material to make fun of him some more. especially because danny has told him he had asked one of them to prom and not only did she laugh she told all of her friends and they all agreed he was punching above his weight.
truth be told steve is all too happy to escape the unwanted attention of soccer mums and some of their bi-curious husbands that were circling him like a bunch of hungry vultures. he would much rather be danny's pretend husband (if it's as close as he gets to the real thing)
everyone cooes over steve and danny, even tho danny knows most of them would not have been this progressive in the 90s, so he privately sneers at what a bunch of hypocrites they are. a part of him, however, enjoys the clear jealous looks of former beauty queens turned soccer mums and bitter divorcées, because yes, he, danny williams, can pull a gorgeous navy seal, whom all of them tried to hit on when they first came on scene, so who's punching about his weight now, brenda?
eventually, they find the information they need, as well as reveal a bunch of other unrelated secrets, and there's even an impressive suspect take-down. danny is grateful that steve helped him get through this unpleasant reunion and vows to somehow make up for one milestone steve had missed out on.
danny: not quite yet. the principal scheduled a do-over dance after that whole fiasco, and i wondered maybe you would like to go with me? it's not exactly prom but ...
steve: *is touched* i would be lucky to go with you.
danny: who says you are getting lucky after?
steve: *blushes* i didn't mean ...
danny: relax, who knows where the night takes us, i always wanted to make out with the quarterback under the bleachers *he winks*
steve assumed danny was joking (he wasn't) but they still spent a nice evening. they didn't have to maintain the cover anymore but neither felt like ruining the fantasy so they even slow danced to 'i'll stand by you' by the pretenders. if only had steve requested another '95 hit - bon jovi's 'always' danny would have proposed on the spot, but alas, they were still bound by restrictive tv gods.
