By order of appearance:
- While Heaven Canceller is talking about Accelerator's brain surgery, he states that he is not returning lost memories, just substituting for lost functions. This may be a reference to the Volume 1 epilogue, where Kamijou Touma's memories are lost when his brain is damaged due to the events of the end of the novel.
- "This is my battlefield, and no matter what, I will return from my battlefield with my patients healed" (Volume 5, epilogue. Said to Yoshikawa when she asked about Accelerator's survival.)
- "I will procure anything my patients need, see? And I've heard all about this. It seems there's a parallel arithmetic network that created the ten thousand clones, too. I'm going to use that in order to restore the lost parts of the boy's brain. What? I'm not returning lost memories, I'm only substituting for his lost functions. It's not that difficult a thing to do, see?" - Heaven Canceller, referring to using the Misaka Network for Accelerator's calculating.
