Simon doesn’t have very many ways to deal with his trauma, so he burns himself. You know about his past, but you didn’t know that he burns himself. When you ask him about it, he’s first defensive and a little mad, but then he slowly opens up to you, telling you why. He never meant for you to find out He’s so ashamed, and it takes him a while to open up. He burns himself because he thought that they would magically go away. he really hates talking about his burns. He did it to himself.
