I didn't really dig her that much, she gave Magus that Amulet, which was neat...I like the idea that Magus keeps that pendant all throughout those years, wearing it proudly & enabling him to avoid all status effects! HA! I somehow figure that's got to be someway he managed to get on the side of the Mystics, because they couldn't poison/confuse/whatever him...^_^
Anyways...she's not developed a lot, but even the small glimpse of her personality in Trigger made me like her more than, say, Marle...>_> But that's not really saying much, I guess...*shrugs* She was a sort of tragic character, forced to go with her mother's insanity and not really being able to do much against it besides when she frees Crono & Co. to try & help the Gurus...and then the crap happens to her inbetween CT & CC, of course...It's interesting that they say she's more powerful than even her mother, and yet she's still compelled to do what her mother asks of her. Definitely a neat, kind of unique personality.
