Hm... Interesting, but doesn't sound quite right... Also, she shouldn't have be sent to 600 CE, but 12000 BCE. (If you look at the order the people are swallowed, Gaspar is first, Belthasar is second, Melchior is third, and Janus is fourth. See a pattern here? Then Schala would get swallowed fifth, presumably, and since she technically is in PD-1 and not 12000 BCE, the time gate would send here there) Plus, I don't think time gates can travel through Time-Error, so I doubt that she'd be able to go to that point in the first place. What transpires there, though, I don't know... I like the idea of her coming to 600 CE and trying to get to Janus, though. I doubt Zeal would be able to banish her, though... Only Lavos himself could do that, likely. You don't see Zealians running around traveling through time/dimension anywhere. (Although they can presumably teleport through space, as seen with the Skyways...) I like the idea of her fighting Zeal, and then Lavos erupts and she's sent to PD-1 along with the Crono crew, and then...something happens? She should only get banished after the events of CT, though, since Lavos has no need for her until he's been banished...
Bah, I suck at this. -.-; Or maybe someone could make a hack and have her be the eighth PC. (I was hearing someone talking about that somewhere...) I like that idea a lot, personally. But an original hack would be nice too.
Eight huh? Good-bye Cure and Pray/Bless then. I feel like Schala would specialize in Heal more than Cure anyway...I think she'd want to heal more people rather than heal one person. Or something. At any rate, editing time! :D
