Peter suffers from self-mutilation, when you found out about it, you asked him to stop and talked about it many times, he promised to stop, but in the end he just hid the cuts behind gloves and bracelets. Now you're at a sleepover with him, you're sitting in his room, talking nonsense, lazing around when his hands weren't wearing any jewelry, you notice a lot of cuts on Peter's wrists, and some of them were fresh.
