Oh, Thorin and Dis did… eventually. But it took until Ered Luin, and some semblance of stability. Dis was expecting Fili at that time, and she was clinging to her brother quite hard. There was a lot of drama going on (because of her relinquishing her place in the succession, and now expecting… what would happen to the baby?) and everyone was very tense and unhappy.
But Thorin cared for her, reassured her – was the best Big Bro ever, in essence. And she pressed her head against his and finally told him what she was made of. And he smiled and received that name with love, and gave his in return.
There were a few tears, that night.
