I am very happy if the game provides feedback on attempts to save Alfira, and perhaps some kind of Easter eggs, if the player knows in advance how further events will develop and acts unusually.
Naturally having ways to creatively approach a situation and solve it differently than expected is always highly appreciated and wonderful, as it gives the feeling that developers care about the little details and makes the game so much better. BUT... it has to feel natural and the player has to have a chance to accidentally discover it or access it through legitimate means through the natural flow of the gameplay.
Unfortunately that is not the case here because it is impossible for the player to legitimately ever experience this scene's 2 out of 3 outcomes, as they are locked behind some extremely unnatural behavior, metagaming and even worse savescumming.
In the end only those who play murderhobos would have the slight possiblity of experiencing Quil at the camp, assuming they decide to murder Alfira for whatever reason before she's supposed to arrive at the camp. But with absolute certainty I can guarantee that no player in the world will ever legitimately experience outcome #3 in which nobody dies at the camp because that involves intentionally killing the player character inside of the camp between Alfira's arrival and resting.
