Did things actually happen as they were stated in the manga here?
Did Mamoru's pocket watch and the Shittenou Stones actually appear and protect Mamoru and Usagi respectively from ever being stabbed and actually dying? Did they both simply pass out at the moment that Usagi used the sword to try to stab them? Did the Inners sacrificing their lives then simply wake-up an unconscious Usagi from inside Metalia?
OR
Did Usagi successfully kill Mamoru and herself? Then either the Inners sacrfice, the power of the Silver crystal, or some combination of the two subtly changed history so that Usagi/Mamoru didn't die instead adding the absurd coincidences of the fainting + watch/stones magically appearing and protecting them.
(The part in yellow is how much of the Holy Sword is not shown...ie how much the pocket watch would have had to have blocked. Does not seem possible unless the sword was made out of rubber. So did Naoko suddenly forget how long the sword actually was?)
*Bottom of the sword image was taken from 2 pages prior with an slight perspective adjustment done to better match the angle of this image. This slightly shortened it*
(An image of the pocket watch that appears at the start of Act 13 after the stabbing. Merely symbolic or a hint that the watch has not been further damaged yet? *see top image for the state of the watch after Usagi Wakes up* Also are those just random squiggles or is that blood coming out of Usagi's stomach on the same page? *there are no other similar squiggles on the page*)
