Liam tended the fractures and wounds of that soldier. The fracture of his hands would have healed within a few hours if he was at the IGT Fed base. But with the limited options from the first-aid kit, Liam just managed to plaster his hand and patch him up for now.
And regarding his missing teeth, he would have to get new ones in a dental clinic. Liam put some ointment in his gum and stopped the bleeding.
After everything sunk inside that thick head of his, he came to realize that he was indeed acting like a bully. And he knew that his career in the IGT Fed was over.
Liam left that man's side and joined the group. To be honest, he didn't even want to help that man for the way he was behaving. But it was a doctor's duty to treat every patient impartially. So he put his ego aside and treated that soldier.
