My fingers are just bloody stubs from writing so much about Game of Thrones, and yet I must go on. A fan had a poignant realization about Know-Nothinger Jon Snow's name that s/he shared on Reddit. The post is titled "Small detail about Jon and Ned that dawned on me today."
I know this has probably already occurred to everybody, but I was thinking about how Ned named his three sons after people who were close to him. Robb is named after Robert Baratheon, Bran is named after Ned's brother Brandon, and Rickon is named after Ned's father. But then I remembered that Jon is named after Jon Arryn, the man who wasn't Ned's father, but raised him like a son. That's a really beautiful detail.
Edit: Glad so many people enjoyed this! Just want to clarify: I've always known Jon was named after Jon Arryn; it's the parallel in the relationships that dawned on me today.
