Nothing can be done. Also, maybe Christoph, due to being "half Royal" might end up with a corrupted core due to the emotional shock of Ryan's death? Ryan spent his last days basically erasing any trace of himself it seems, in order to protect others. Sihan and Karis's response still hasn't been shown yet, just Christoh after he had his memory wiped, and Kyon & Lucaon's.
Why not enjoying his last days with cristoph ,, why hurry in earasing his memories,, and y is no one doing anything to help Ryan
