Regarding this, I'll say that I can't see Mallow, Lana and Sophocles getting new Pokemon- I could be wrong, though. But the reason I think this is because of their goals- Lana's Bubble dream, Mallow's cooking goal, Sophocles probably doesn't have any. Plus, with Ash and Lillie seemingly getting more focus, these three+Kiawe will probably get less focus. With Kiawe specialising in battling, I can see him getting an Alolan Marowak. Regarding Lillie, I can definitely see her with a Cosmog(most probably befriended), during the Aether Foundation arc. That's all I have to say in this regard.I agree, for the most part. I can see Mallow and Sophocles each getting one more Pokémon, and I don't think Lana will get a third Pokémon. I can see Kiawe maybe getting an Alolan Marowak (since it's so associated with him in the game). Lillie, on the other hand, probably won't get another Pokémon--not until she has completely conquered her fear of touching Pokémon (which I don't expect to happen until much later in the series). She will probably end up being Cosmog's caretaker, and she will probably become attached to it, but it won't be her Pokémon.
