Sylvia indeed follows Skinwalker out to the training ground, and she was willing to listen to Skinwalker when she mentioned that she wanted to teach her and Shortfang how to use ammunition as melee weapons if they needed. Sylvia thought that would be a useful thing to know, especially if they find themselves in dire straights without any other weapons at hand. Sylvia took the lesson to heart and practiced the technique until she had mastered it. After doing so, she thanked Skinwalker for teaching her. 

After that lesson was finished, she would try to get herself acclimated to the horrible stench coming from the troglodytes bodies.
