After the Battle of the Five Armies

It was getting on for the evening. All of Azog's warriors had already fallen, well, like everyone else... (In short, I don't give a shit that Bolg had fallen into some asshole somewhere; he was supposedly alive, but no one knew).

All the dwarves who were still alive quickly hurried to Raven Heights, where Thorin, Fili, Kili, and Dwalin were fighting. Balin met Dwalin there. And Balin and Oin quickly approached the three bodies; they were breathing, and found the three poor things. Oin said

Oin: Quickly, there's a pulse, we can save them...

Balin turned to Dwalin

Balin: Dwalin, take Thorin! The rest of you, take the Boys if you can! There's no time to waste!

The Elderly Dwarf said loudly.

In the Hospital Wing of Erebor

Oin looked at the three bodies on the beds

Oin and Balin noticed Ori lounging around doing nothing.

Balin: Ori, please help us.

Ori winced and asked

Ori: What? But I'm not experienced yet, and I don't know...

Oin: Practice is the best teacher, quickly get the medicine and help us!

Ori nodded and quickly left to get medicine, settings, etc.
