Aria found Adagio, but that was only the first step. Sonata is missing and has been for some time, and without Adagio's magic, Aria knew she had no chance of tracking their sister down. Aria's only clue is that Sonata crossed the ocean to Manehattan, and beyond that she can only pray she and Adagio can pick up her trail.
In the meantime, the memory song that stripped Adagio of her painful past few decades has left her with difficulty focusing and remaining lucid. Through it all, Aria can only pray that she can pick up the potentially decade-old trail left by Sonata and find out the true nature of the danger she's found herself in.
