from the beginning they’re intended to have a relationship that blurs the lines of familial and mentor/apprentice so their recent appearances/interactions build off of that rather than changing anything! “officially” their dynamic is that of a general and retainer (yanqing assists him and jing yuan in return teaches him the art of swordplay) but jing yuan is also the closest thing to a parental figure that yanqing has since jing yuan took responsibility for him, raised him, cares very deeply for him and does whatever he thinks is best for him. jing yuan doesn’t outwardly refer to himself as a father or to yanqing as his son though, which i think is what contributes to some confusion about their dynamic, and this emotional distance is bc of his own experiences, emotions and beliefs surrounding interpersonal relationships and duty. their relationship is intended to be nuanced and dynamic so i’m looking forward to how it continues to develop over time! and please keep in mind that what i’ve said here is not meant to be comprehensive! this is just a brief recount of what we’re given in canon
