I a have few things ask. More like a theory and a nogging question.
1)Dorren is Masa and Mune's older sister, so she should similar ability to change she form of people or objects. Has it been stated that she was ever an item before join to form the Mastermune?
2)I believe that Masamune would of been puifed, even without the events of Serge fighting Dario. The Masa and Mune were awaken by Dorren, who apparently been searching for them for a while. With them up, they released the evil-energy on their own. But I can't remember much of the later, lesser parts of Cross. Can someone remind me about what happen to the Masamune after Lynx took it?
3) This isn't related to the others, but it's be bugging me for a while. In Crono was "killed" by Lavos in Ocean Palace, what was point of that spark-thing floating out of him? Was is his soul? The clone others used to save him? A random refence to a old folktale? It just seemed pointless.
