It is also similar to an internal monolog given by another chacter from a diferent manga. The chacter was about to go on a very dangerous attack run.

Moon ejected her own heart crystal so she could go after Saturn. I don't think people with their heart crystals ejected can do much, and we see Saturn die on screen and just make a new body for herself. Personally I think Saturn may have saved Moon, and there is some evidence to suggest Usagi was draining energy from Saturn during and maybe after the fight with P90. .
In the anime we don't see the battle with P90, Pluto die from time stop, or EUDIAL die. The next time you see Pluto is at the end of S, and Hotaru seems to still remember things even if she is in baby form. In the manga you do see Pluto die from time stop.
