I'm pretty sure that the champion WILL be someone we met already- even briefly, but I'm sure Ame stays dead. (Probs will be Lin as everyone already said)
Shade will definetly get more involved in the story, I'm not sure how. A npc told us that someone got mad trying to beat Shade, they might get involved as well.
Arceus will definetly be a boss or something among those ranks, and El will have something to do with it (ofcourse lol)
Anna (and Noel?) will surely play a major role in EP19 as well. I'm willing to bet that Anna has something to do with Lin 100% anyways.
