I was saying that Yukino's claim about the 12 Golden Keys need to be united as speculation, not your speculation.

Also back then in the GMG/Eclipse Arc, it was because of the Eclipse Gate that the 12 Golden Keys was focused on, now that the Eclipse is gone, you don't see there being any focus on the Keys instead now it changed to how to summon the CSK.
