Rinoa probably will end up being imprisoned by Esthar. There's no way for a sorceress to keep sane 24/7. Humans =/= Sorceresses.

Those sorceresses you saw were created by TC. They may be real, but I don't think that thier appearance is real; the developers were lazy on that part.

I wouldn't worry about Squall. He's already dead. At least Rinoa has her own holographic device for that ...
