One day, there was a stir of excitement surrounding one of the new arrivals. Talk was that he had found a cure for the lycanthropy that plagued the Companions. He said that he had sent one of his most promising members to investigate his findings shortly before Jorrvaskr was attacked and he was cut down in battle. He assured those surrounding him that, if his theory was correct, the Companions would soon be free of their curse. As she usually did, Ylwa began her wait for all of the catching up with the new arrival to settle down before seeking a time to quietly do her standard questioning regarding Farkas's and Vilkas's health and well-being. For this particular arrival, there was excitement even amongst those who didn't know him during his lifetime. While not catching up with those old friends who had arrived before him, he was almost constantly bombarded with questions from one interested person or another regarding the cure that he had hopefully found. He had not a moment to himself. Ylwa felt sorry for him.
There was a buzz of excitement and some drunken celebration going on in Jorrvaskr when Ylwa returned from a run. It didn't take her long to discover the root of everyone's joy. Kodlak, the man who had arrived recently, had disappeared. He hadn't been killed and forced to find his way back to Jorrvaskr. He had just vanished into thin air, meaning that the cure had worked. Those who desired Sovngarde truly had reason to celebrate that day, as he had promised since his arrival that, if he was cured, he would come back with greater numbers and rescue them all from the clutches of Hircine.
Everyone put their affairs in order. They said their goodbyes to those who did not intend to leave the Hunting Grounds, and they lived every day there as though it might be their last. Kodlak did not show up, though. Those who knew him when he lived assured the others that there was no reason to doubt his word, that he would still be coming. He must be waiting on something, or working on collecting the numbers he needed to invade the daedric prince's realm, or even looking for a way to get back into the Hunting Grounds to steal his Companions away. After some initial doubt and bitterness at his not arriving imminently, the majority of the Companions made their peace with the fact that he would be coming back eventually. Things gradually returned to roughly what they were before Kodlak's arrival and disappearance, but everyone was a bit more optimistic.
Ylwa had some doubts as to whether she would be able to go with the Companions when they departed for Sovngarde. They had become family to her, and she hoped that Farkas and Vilkas would be wherever the Companions went if they were to ever meet an untimely demise. They seemed to accept all sorts, so she felt mostly confident that she would be allowed to accompany them. Those few whom she felt the most comfortable with assured her, when she opened up to them about it, that she would be allowed to go with them to Sovngarde. So Ylwa waited with the rest, hoping that somehow through all of this afterlife-jumping, she might find a way to jump back to real life and be with her beloved boys again.
