Quinn has suffered from a severe spinal chord damage. Her spinal chord got pressed and squeezed in between her vertebrae. I don’t know if you know what that means, but basically her neurons and her nerves that control her legs movement (which are scarily close to the ones that control her breathing and her heart contraction) have been squashed together.
She is barely able to walk again, with the use of a prop to help keep her steady.
Then Finn lunges at her, trying to knock her wheelchair over, or trying to push her to stand up. He could have done some severe damage.
I don’t care how angry he was. I don’t care if Quinn was doing that for the wrong reason. I really don’t care about the context, because in violence, context just doesn’t matter.
If you can’t control your teenage level of testosterone around a woman in a wheelchair just because you’re angry at her, I don’t know how you’re going to live your life.
