Flashback moment, this conversation takes place a bit after Zhen Liu had blasted Zhen Hai in the face with the knowledge of defibrillation and then has Logos and Pathos scramble the latter's memories.
"So...you guys are certain he won't remember how I blasted him in the face with a faceful of kaijin?"
=That should be the case, yes. We are very skilled at manipulating memories.=
"I mean I believe that, but even I know there are exceptions to the rules. Do you know of any possible ways he can suddenly remember that it was me that gave me that knowledge, well, enabled Hurricroak to bestow that knowledge?"
<Actually...yes. If for whatever reason he ends up in a situation similar to the moment we just scrambled, memory will unscramble itself about...ninety percent clarity. As long as event happens within three months though, after that, scramble is permanent.>
'What about that last ten percent?'
