Oh, I found a chilling comic a few days ago on Reddit that I totally forgot to link here.
WHAT HAPPENED ARG.
It's hard to say.
We know that the successful brother shot a wolf, and claimed it was the monster. We know that the unsuccesful brother claims to have killed his brother, but we never see the act, only the aftermath of his brother being dumped into that hole. The deep, deep hole in the middle of the forest, which is suspicious by its own. We know that three days later, somthing that looked like the succesful brother came out of the woods wearing an intact coat, somthing that shouldn't have been possible. We know that the thing claiming to be his brother won't look the unsuccesful brother in the eye, and digs at night while the unsuccesful brother has nightmares. We know that somthing looking like the succesful brother's dead body was at the bottom at the hole, and
it freaking turned to look at the unsuccesful brother when he climbed down to check on it.I think the hole has somthing to do with it. While the tale of "The Monster In The Woods" is present, I suspect it to be a red herring, as the "monster" is discribed as doing nothing that a particuarly hungry lone wolf could not do. The hole is the first real strange element, smelling of lilacs. There's no reason for that, but lilacs show up twice before, once at the succesful brother's home and once in the woods. I don't know why.
I think that the unsuccesful brother murdered the successful brother to get his stuff, ands the hole was the real problem. Note that in the page before the brother's corpse is seen, his body kind of looks like the wolf he killed. I think that, perhaps, if a dead body of anything ends up in that hole, three days later a malicious facsimile is created. The original wolf fell into the hole by mistake and died. Three days later, the copy wolf was created and began hunting down animals simply to do so, not for food. The original brother was murdered and thrown in the hole. Three days later, the copy brother was created and came back to drive the unsuccesful brother back to the hole to check. There, the brother's corpse was animated by the hole and killed the unsuccesful brother, scoring the hole another victim.
