In the Episode 2 when TJ talks about witnessing someone dumping Lily's body, which was glamoured as Snow's body, he give very strange information to wolf. He said someone was saying "stop laughing". If we ask him for the exact word he says "They said, stop laughing at me".
This is really a minor evidence but it made me think for a long time. In what kind of situation can a person who was dumping dead body into the river possibly say "stop laughing at me" to his workmate? just what can make him look so hilarious? dumping Lily's dead body was funny? clearly not.
After long thinking I concluded that if the culprit was wearing donkeyskin for some reason while dumping the body it would be hilarious enough to make his friend laugh. That was the only reason that I could think of with given information so far. Why was he wearing it? How did he get it from toad's apartment? I have no idea.
Still this is just a guess about what might have happened, so I really want to hear more about how everyone think about TJ's testimony. I'd love to hear any opinion about this. Corrections and criticisms are both welcomed.
btw sorry about my grammar mistakes if I have any, this is not my first language
