I hated the story because of it Ryan was my favorite wasn't clear what happened to him the story was rushed no one tried to help him no one even felt sad for him even a little and the thing with Chris just ruined it all for me very good story with a very bad ending
I think he wanted to erase christoph's memory so that he wouldnt corrupt his core with the news of ryan dying. Ryan was scared of chris turning into a zero coz he cared too much. And since there was no way he's gonna get cured coz its been 10yrs since ryan core got poisoned, he had no choice but to resort to leaving christoph, which made him really sad if you notice when he kissed chris goodbye
No no no...bring Ryan back alive please. How can he do that to Chris. That's not nice is better to love and lost than not love at all. You should of left him with his memory. I don't like that part one bit.
