The only way to remove the gear from Noo's throat is to resurrect him. For some reason neither you nor anyone else simply removed it from his corpse, and somehow resurrecting him with the fatal blockage doesn't immediately re-kill him. This especially stands out because of how the rest of the story cascades from this one detail.
Fridge Brilliance
Considering the Evil Faerie can move within stopped time like the player, it comes across strongly as a narrative conceit that he doesn't kill everyone before they even get the chance to move. That he paces around the cabin while other characters are vulnerable feels like a case of Monster Threat Expiration with his time stop being as Strong as They Need to Be. Once you learn that human faeries are under a constant, feral rage, however, and the Evil Faerie's behavior starts to add up. He doesn't have the mental capacity to comprehend that there is a group of children in his forest, he is only wandering around until he finds a target and then tunnel-visions that target until he has stolen its time.
The fact that the player character is small is initially justified by the fact that you're supposed to be a faerie. The Evil Faerie, however, resembles an adult human. It turns out you're not small because you're a faerie, but because you became a faerie while still young.
The divide between the main plot and the Story Breadcrumbs can be noted as the difference between what matters to a child versus what matters to an adult. The plot involves playing pranks on the other kids and helping them out with things around the boarding school while they offer their thanks in return. When the plot gets dark, your actions are a very direct reaction to seeing your friends be hurt, and the game ends when you undo the direct threat to your friends. The Story Breadcrumbs, however, paint a much more complicated plot of conspiracies and regrets, of adults making bad decisions, contemplating suicide, and causing lasting damage to the world around them. The game ends with the consequences of this half of the story unresolved, with Margareta still having wounded Rosza and the Evil Faerie still haunting Robb's Forest. Considering you learn that you are Alexis, one of the children yourself, your lack of initiative toward the actions of the adults make sense.
The fact no one does anything about the Evil Faerie does make sense, in that the Faerie will eventually get enough life force via some method, perhaps hunting wild game, to travel back in time. Since the Evil Faerie remains in a loop, as it will obviously fail at its goal and need to go back in time again just like us, it will cease to exist in all future timelines past that point. At least for the kids, their personal timeline will now extend past that loop.
Fridge Horror
The fact that the Evil Faerie was never dealt with in any of the timelines, meaning that he is going to keep killing anyone unfortunate enough to wander into Robb's Forest. Worse, he has the power to time travel himself, whatever it is that he uses the power for.
