I'd look for stories set around the Medical Department's day-to-day. The moments where their professionalism slips, not the big crisis events. A fic I can't recall the name of handled it perfectly—Saria needing to rest but refusing, Link insisting she take a break not out of soft concern but because an exhausted defender is a liability. Their dynamic shines in the quiet, procedural stuff: inventory checks, debriefings, the unspoken understanding when a treatment fails. The friendship isn't in declarations; it's in how they share space without needing to fill it.
Avoid anything that makes it secretly romantic or overly sentimental. Their bond is built on competence and mutual, grudging respect. The best ones have them disagreeing on methods but never on the core goal of protecting Rhodes Island. I've dropped more than a few stories where Saria gets softened into a generic caretaker or Link becomes a pushover. The tension is the point—it's what makes their eventual, hard-won teamwork mean something.
