Also worth pointing out is that when Fixing RWBY does the stupid "silver eyes erode your memory" reveal, Maria telling them this is preceding by her asking Team RWBY if they are willing to sacrifice
Ruby Rose, in the sense that their friend may become someone who doesn't remember them and the times they shared.
In fact, WBY's responses are even very similar to when such a topic comes up in
Volume 9.
Given the fact that Celtic Phoenix is a talentless hack who can't come up with an original idea of his own when it's not fuelled entirely by him being a misogynistic pig, I have zero doubt that no matter how much him and his flunkies claim otherwise, the loser actually ripped off a plotline from the currently-airing volume solely for the sake of
padding for his shitty rewrite.
(And the bit about Team RWBY not getting along in V6 is entirely Celtic Phoenix and his groupies being misogynistic fucking losers who think women can't get along for five seconds and will start squabbling for the stupidest reasons.)
Edit: Also, it just occurred to me that if they wanted memory-loss from the Silver Eyes to be a thing, that's probably something they should have foreshadowed. If only there was an instance in Volume 6 prior to Argus where Ruby made use of the Silver Eyes...~
