Here be dragons!
Spoilers follow for the season finale of Game of Thrones.
You've been warned.
I'm not going to whip up a fan theory on how the eight season long tale of Westeros is a Rare disease parable. Bran is wheelchair bound after a fall, not due to a disease. Maybe we can argue Tyrion's dwarfism comes from Achondroplasia (not rare, but it's a mutation of the gene FGFR3) which affects actor Peter Dinklage. But the show was never about that, cause you know science.
Instead Bran. Bran abides. Bran endures. Bran persists. He overcomes. He gets vision and wisdom. He gets a wheelchair. And ultimately the wheelchair is the throne. Yes, the coveted titular throne, the iron throne forged of the swords of defeated rivals, literally melts away into irrelevance.
And upon what new throne will the new king sit? A wheelchair! I love it.
And I kinda predicted it. Or maybe my ten-year-old did. October 2018, Lucas dressed for Halloween in his wheelchair as Bran on the Iron Throne. Some thought it inappropriate. His school had an explicit no costumes with weapons policy. I'm sure many asked “Are they really letting their 10 year-old watch that show?”. For the record at the time we were not. So yeah I can't say Lucas was a fan of the show or had any insights into it. It's totally dad projecting his fandom onto his kid who can't speak up to pick a different favorite costume. But this spring Lucas did begin to watch GOT when his nurse was at our house. They'd watch together and he really responded to the spectacle of the dragons. A favorable response, not a terrified freak out.
Someday we can argue (or maybe right now in the comments section) the merits of Westeros voting in another white male. I mean they'd have no issue voting for a qualified women to lead them, just not that woman. Right? And why do we have to call him Bran the Broken? I don’t know, maybe they get a pass since this is set before the Age of Enlightenment. But all that aside, exulting the kid with disabilities to the highest office in the six kingdoms? —that works for me.
