Man, trying to rank SBG pairings feels like picking a favorite child sometimes. For Tyler x Aiden, the 'reluctant allies to lovers' arc just hits differently than the others. It’s not as flashy as some of the bigger canon ships, but the tension of them being from rival factions, forced to work together, and slowly dismantling each other’s preconceptions… it’s a specific flavor of slow-burn that really works for them. Writers who nail that progression, where the trust feels earned and the shift from suspicion to protection is gradual, create the most re-readable fics.
That being said, I’ve noticed a ton of variation lately. Some people go full-on action-adventure with them as a spy duo, while others focus on the quiet, post-mission recovery moments where the masks come off. The quieter ones tend to stick with me longer, honestly. There was this one fic where Aiden was injured and Tyler had to basically babysit him in a safehouse, and all their bickering just dissolved into this exhausted, vulnerable silence. It didn’t even need a kiss to sell the connection.
If I had to name a top storyline though, it’s probably the 'undercover as a couple' trope done right. It’s a classic for a reason, but with their established dynamic of mutual annoyance, the fake-dating feels especially charged. The best versions of that plot don’t rush the 'falling for it' part; they let the characters be hilariously bad at the performance before the lines start to blur for real.
