The dwarves’ physical state in the Halls of the Maker corresponding to their mental state though-
It takes decades for Thorin’s wounds to heal and they break open at the most unexpected moments. The worst was when he saw Kíli in the Halls for the first time. He is never fully whole again, although it does a lot for him to finally receive his sister’s forgiveness. The moment the last of his wounds, the one on his forehead, is completely gone is the moment when Dwalin, the last of the Company to die, finally joins them and feigns a punch in his face and then hugs him so hard he thinks his bones will break. (It is then that Balin’s wounds finally heal too, he who had sat in the Halls for hours with Thorin, talking about how they had both let go of their lives when there would have been so much more to live for)
Thrór’s throat kept bleeding for so long that he took to wearing clothes with high collars in the Halls. It takes his family a long time to bring him back to where he was - and only when both Thráin and his three grandchildren arrive and tell him just how much he meant to them despite everything that had happened does he dare to wear more open clothes again.
Everybody thinks Fíli is okay. He puts on a brave face, spends a lot of time with his brother, his family and tries to comfort his uncle. Nobody sees when he withdraws to his chambers from time to time, hand coming away bloody when he presses it to his chest under the clothes because he still thinks he failed them all. It is Frerin who finally picks up on it first (apart from Kíli of course, but Kíli knows everything anyway) and takes him aside for a talk, a small patch of blood blossoming on his own chest where the arrow had hit home so long ago for a moment.
Kíli always laughs, looks unharmed and brightens everyone’s mood. He is everywhere at once, meets family members from all branches long dead that he is never known - he seems as alive in death as he ever was. Only sometimes, when he looks at his brother and his uncle, who shouldn’t be here, who he thinks he should have protected because he is the spare, it should have been him who died, not them- he flinches slightly, hand rubbing over his chest where Bolg’s weapon had found its mark.
Dáin has tumbled in the Halls with a curse on his lips, but his wounds that still oozed blood for hours after he has woken up - he left them alone in the midst of battle, selfishly withdrew and died when nothing was safe yet - close up quickly when he hears a quiet grunt and a giant boar throws him to the ground, rubbing his enormous face on his clothes and he sees the smiling faces of those who await him.
Dís follows him not long after, fallen, too, defending the mountain her kin died for. She lightly punches Thorin only moments after Dáin did and her brother carries a brighter smile than he has worn in decades when she’s finally there. Her wounds had closed the moment she had woken up - she knows she has given everything she had for the mountain and her people and could go in peace, to finally be reunited with her family and friends again.
