It kind of looks like the knives Valentine threw didn't register as projectiles but rather as part of her body, so when they collided with the George, she took damage and knockback, but maybe had an unflinching frame from the properties of the blockbuster so she instead crumpled.What i think he means happens at 2:32; valentine uses her checkmate blockbuster and at the same time his peacock uses a george special move just when shes about to get hit, the attacks “cancel” each other out and both receive damage, the Valentine falls down as if defeated saying “lucky” and then gets up.
