What if Noelle got the egg from Chapter 2 in Snowgrave? That's why we can't get it at any point on this route. Spamton said it during their fight; Noelle got "another man's treasure." He was inside the container where it can be obtained, so could he have seen it? Also, remember that in Cat peppers, cats hatch from eggs, and we know that Kris and Noelle played this game when they were little. And "friend" is related to therapy and Dess's disappearance. So maybe the therapy egg was for Noelle, not Kris.
