>>578Yeah, I agree. The thought sort of occurred to me halfway through writing that post though, so I just finished my thought and appended that to the end. The satoshi part, however, does fit I think since we can most likely assume that during her traversal through the kakeras she figured out his location, and figured out how to get to him. It makes sense that with this knowledge she could just visit him in the hospital at any time if she put her mind to it. It could probably have been in the first arc of Gou for all we know.
Also now that I think about it, when they found Rika and Satoko dead in the first arc, Satoko most likely killed Rika.
