The girl was forced to marry General Caraway (rinoa's father) or something after Laguna left. Didnt know the last song was from her.
Ellone was kidnapped as potential sorceress by Esthar, and Laguna tried to saver her. He ended up getting captured, escaped, beat Abel and somehow become president of the city.It seems like Laguna gets Raine pregnant but doesn't know about it, and then he goes off with Kiros and Ward once again (they never really explain the reasons behind his departure from that village in the beginning of CD2... Winhill is the name I believe.)
