How Does Merlin/Gwaine Fanfiction Explore Their Trust And Loyalty Dynamics?

It often feels like a study in different types of loyalty. Gwaine’s is boisterous, sworn over ale, but no less solid for it. Merlin’s is quieter, shown through actions—healing, protecting, lying to keep Gwaine safe. The trust isn’t in sharing secrets; it’s in knowing the other’s character. Gwaine trusts Merlin is good. Merlin trusts Gwaine will stand by him, secret or not. That unspoken agreement is the core of most fics I enjoy.

Ugh, I’m so tired of the ‘Gwaine is Merlin’s unshakable rock’ trope. Don’t get me wrong, I love them, but it flattens both characters. Gwaine isn’t just a loyal puppy. He’s a knight with his own code, and he’s shrewd. A lot of newer fics I’ve seen play with Gwaine’s loyalty being more conditional and pragmatic than fanon usually admits. He trusts Merlin’s heart, but maybe not his judgment when it comes to self-sacrifice. That conflict is way more interesting.

I read one where Gwaine found out about the magic not through some emotional confession, but by catching Merlin in a lie about where he’d been. The fallout wasn’t about betrayal; it was about Gwaine being furious that Merlin didn’t trust him enough to handle the truth. The loyalty was still there, but it had to be rebuilt on new, honest terms. That felt real. Their dynamic works because Gwaine’s loyalty is active, not passive. He chooses it daily, and that choice can be complicated. Makes for better stories than the same old ‘steadfast knight and his secretive sorcerer’ template, anyway.

Honestly, I’ve always read the trust between Merlin and Gwaine as fundamentally one-sided. Gwaine pledges loyalty because he’s the kind of man who chooses his friends and sticks by them, period. He trusts Merlin instinctively, from the moment they meet in that tavern brawl. Merlin, though? He can’t fully reciprocate. He’s carrying the weight of his magic and destiny; every genuine bond is a risk. So many fics I love dig into that asymmetry. Gwaine’s loyalty becomes this unwavering pillar Merlin leans on, all while Merlin is quietly, desperately protecting him from the truth. It creates this beautiful, tragic tension where the trust feels deep but also fragile—because it’s built on a secret.

Some writers flip it, of course. There are stories where Gwaine figures it out, or Merlin confesses, and then the dynamic shifts to a fiercely protective pact. That’s when you see the loyalty tested not by external enemies, but by the internal strain of the secret itself. The best ones don’t just have them become co-conspirators; they show Gwaine grappling with the danger Merlin is always in, and Merlin learning to actually rely on someone else for once. It’s less about grand gestures and more about the small, earned moments—a shared glance, a covered patrol, a silent understanding when Arthur says something prejudiced. That’s where the real character work shines.

I guess what I’m saying is, the fandom uses their dynamic to ask what loyalty means when one person can never be fully transparent. Is it still loyalty if it’s given blindly? Is it still trust if it’s conditional on ignorance? They’re perfect for exploring those questions.
