[When Dís told him that he, Thorin, and Fíli died at Erebor, Kíli was a mess for nearly a week. Not that anyone who wasn't a Dwarf would have been able to tell, but he'd been much more affectionate and clingy where his mother was concerned--and given that he was already pretty physically affectionate for a Dwarf, he was worried Dís would have smacked him if he hadn't eventually calmed down a little. He doesn't even mind it when he thinks his mother is treating him like a younger Dwarf. He never should have gone on the Quest.

Walking around the cottage and down the path didn't hurt, not until I sat down for a few minutes. Still, that's progress, isn't it? Soon I'll be runnin' around and giving you grey hairs again.
