I'm pretty sure Aquarius won't be appearing again anytime soon this arc. The last time she did appear, was to solve the misunderstanding Brandish had towards Lucy's mother. She also appeared to confirm that her key was remade somewhere else, sort of setting a departure for Lucy to go look for her (as in, "we'll meet again"). If she appears again for the reason listed, I will be highly disappointed in Mashima.
