It looked like an old guy was in the medical tent, towards the end, who was stabbed in the side by something. It was just shown in passing, so I'm not sure what that was about.
The deadnaming scene is quite intense since it was used as a punishment. Also the character who was deadnamed apologized first, before the other character apologized.
The coach intentionally misgenders a trans woman during an argument. Discussions about her identity are handled transphobically by certain characters. (I know some people socially transition because the Samoan government is homophobic but this character is based on a real person and we have no reason to believe she isn’t trans)
