So I rewatched "Jumpin' Jack Flash," aka the best spy movie ever made, and looked to find that there is ONE fic for that movie and it's not even a Terry/Jack/Peter OT3 like God intended and so sometimes you have to be the change you want to see in the world
Peter catches a flight to DC the day after Jack and Terry finally have their dinner together.
He’d planned to stay in New York for a few more days — catch up with Jack, make his case to Terry again that she had the makings of a world-class Company woman, find out what had actually happened these past two weeks while he’d been flailing around undercover and the two of them had apparently been taking down the biggest mole operation in the past ten years — but then he goes to Jack’s apartment that morning and knocks on the door and Terry opens it.
“Mart— Peter, fuck, Peter, Peter, I swear to God I’m gonna get it eventually, see, this is why I can’t be a spy, do you understand what I'm saying?” she laughs as she ushers him in, all sunshine grin and and sparkling eyes. She’s wearing one of Jack’s rugby shirts that hangs halfway down her thighs and a pair of penguin-shaped slippers, and it’s like getting smacked with the tennis racket all over again. Only this time he doesn’t have the luxury of showing the pain.Instead he has to smile back and shake his head as she takes his coat, has to follow her in where Jack’s already making breakfast — “Something called a full English, which I’m pretty sure is what I had last night,” Terry says, nudging Peter in the ribs.
“Complete with sausage,” Jack replies as he pulls out a third plate. Terry laughs. Happiness looks good on her. Good on them both. When was the last time Peter had seen Jack happy? “I’ve champagne in the fridge, sweetheart, if you’d be so good.”
Peter turns to Terry, to offer to get it instead, but she’s looking at him expectantly. “‘Sweetheart’ is your nickname now,” she informs him. She makes a big show of propping her elbow up on the counter. “I told Jack I’m only accepting ‘darling.’ He says it so nice, don’t you think? ‘Daaahling.’ Not an ‘r’ in sight, it’s great.”
“Sure,” Peter says around the stone in his throat, and he slides off the stool to squeeze past Jack to his fridge. There’s champagne and orange juice, along with a half-dozen things Jack’s never eaten in his life and probably wouldn’t at gunpoint: Terry’s favorites.
He manages to eat something, though when he thinks back on it later he has no idea what it was or how much, and makes his excuses as quick as he can. Terry gives him a kiss on the cheek and retreats to the bedroom to change, but Jack walks down the stairs with him and down to the street.
“I’ve put in my resignation to Department C,” he says, without preamble the way he always does. Jack’s never believed in small talk with his friends; he’s claimed for years that it’s because with friends, you grow closer through silence, but Peter thinks it’s just because he hates the tedium of it. “They weren’t happy, but Archer’s made noises about a job at the company, which may prove more suitable. Considering,” he adds with a glance back toward his apartment.
It conveys a lot. Too much. But Peter’s field assessments have always lauded his attention to detail; his care in confirming information. So he can blame his training for the way he says, “So you’re serious. About,” and he gestures back in the same direction.
Jack looks up at him, surprise in his expression. Is he surprised? Jack’s had flings before: with civilians, with other agents. There’s a persistent rumor that he and Talbot had some sort of mutual understanding for a while, which was why Talbot had such an easy time convincing MI5 Jack had turned; no one can betray you quite like the people you’ve slept with. Or the people you love.
“I’m serious,” Jack says, and Peter nods and claps him on the back and hails a cab and gets the hell out of there.
