It's always been fascinating to me that he hit me where I live more than anyone else - however grateful I am, and I am! about characters who match the more visible parts of my self in terms of gender/sexuality/ability/etc - because it sort of told me that actually, when it came down to it, "elder sibling actively invested in a semi-parental role and incredibly protective/attached" was apparently a more central part of what I lived as my identity than anything else.
Whereas the sibling who's the other part of that in my life, who is a blonde-pink-blue-eyed Autistic young woman, hyper-IDs with Worf, because of all the time he spends staring at his human crewmates going " . . . . wut."
