I believe that's the point, Emerald and Mercury being sidelined. They were awesome villains who caused an apocalyptic event to take Vale down, but they are big fish in a small pond, or they were until they came to Casa del Grimm, where they have to eat next to Deathstalkers and worry about Metroids staring at them as they sleep. It kind of shows how unimportant they really are in the face of Salem and Co. (Also, they probably couldn't get Yuri Lowenthal to come back, so Mercury's been left mute).

As for Yang's arm, I'm still thinking of Rocky IV and thinking she's gonna end up climbing a mountain on her own, and upon reaching the top will activate her semblance (and it will be awesome). On a slightly more serious note, she probably will do something dangerous eventually (maybe on accident), but the adreneline rush would remind her of how she used to want to do that all the time and cause her to focus to get out of her funk (maybe with the help of an American Ninja Warrior-style obstacle course).
