Okay, so I’ve fallen down this rabbit hole way more than I’d care to admit. With Randy and Theresa from 'Army of Two', it’s less about sunshine-and-rainbows romance and more about the grim intimacy of shared trauma. The canon gives you this foundation of two people who’ve been through absolute hell, and the fanfiction really leans into what happens after the adrenaline fades.
A huge theme is recovery, but not the clean kind. It’s messy, with nightmares and panic attacks in safe houses, learning how to be a person again when all you’ve been is a weapon. You get a lot of fics where Theresa’s medical skills translate to patching up Randy’s soul as much as his body. Another angle is protective custody scenarios—forced proximity where they’re stuck in some safehouse, and all the walls they’ve built up start to crumble.
I’ve also seen a weird amount of ‘undercover as a couple’ plots, which I kinda dig. It plays with the tension between performance and real feeling, having to sell a lie that gradually stops feeling like one. The dynamic is always this push-pull of brutal pragmatism giving way to something fragile, which fits the game’s tone perfectly. It’s never fluffy, always grounded in that gritty, weary atmosphere.
Ends up feeling like a study in trust, honestly. How do you trust anyone after what they’ve seen? The fics that nail it show that process, slow and full of setbacks.
