Of mine I think the major plot potential exists between Zell and Fujin, and Red and Fujin. Zell is a spaz who sometimes has problems letting go, but they're both adults now. They're both instructors. I feel like their working relationship has been cordial but a bit on the frosty side. He'd jump in to help fight off a T-Rexuar but isn't going to sit at her lunch table, if that makes sense.
However, he's junctioning again for the first time in years to show solidarity with his students. Zell doesn't really want to, but doesn't think he can expect something of their cadets that he's unwilling to personally take on or unprepared to teach. Unfortunately, his compatibility with Ifrit has plummeted and he's suffering heavy losses. There could be something to build on?
Red is all about the wind magic and might have studied under Fujin depending on how long she's been teaching. She's junctioned to Pandemona and the two have a reasonably functional relationship. Red is pretty glib about sacrificing memories, especially family related ones, so long as they don't encroach on her present relationships. I think it's easier to take memories for granted at her age. BUT YEAH. Red would have mad respect for Fujin, but is no stranger to clashing with authority figures. Whether their dynamic is positive or negative could be determined by in-game interaction :)
