I could just tell you what I know
Or you could find it yourself for once instead of waiting for someone else to finally point it out :)
EDIT: Here are some expert resources for those who can't look back a day phase to find the posts

We're not always going to assume that you're correct that these "clues" you're alluding to are legitimate, which is what makes the "I see something you don't see" game fruitless.
However, from the post about the hag, I'd say that this indicates either that the prophet gets a free kill whenever they correctly predict someone's death, or they get a free revenge kill when certain roles are killed, a la Lucifer in FDL. I'd lean more towards the former, since Melody's death was easily predictable (which would also mean that this hypothetical prediction ability goes by player rather than role).
