As off-color as it may seem, there's always drinking and porno. He'll probably ride his fame as a famous ninja, eventually learn to be humble, yet continue his flings with numerous ladies without ever feeling satisfied, become real disappointed/depressed when Rydia meets up with someone more right for her, until he meets some ninja princess with super kung fu skills whom he didn't expect to fall in love with and then live comfortably ever after.

Uh, but for those who think Rydia and Edge get together, I'd imagine they'd turn out much like Yang and his wife, only with Edge being real irresponsible compared to Yang, of course. Comic foibles ensue and we are taught to laugh at love again. Pick either scenario you want. Personally I think the latter one is a lot more light-hearted.

What EXACTLY did Kain do after Rydia first summoned Titan at him and Cecil causing a huge destructive earthquake? Did he wander around confused until Golbez found him, did he wander back to Baron on his own and become brainwashed/assimilated that way, or did Baronian guards send to spy on Cecil and Kain find him and escort him home?

In fact, I want to change my question to this instead: What transpired while Cecil and Kain were sent off to unknowingly destroy the village of Mist, until at least Cecil met up with Tellah? What we can probably assume is Rosa and some Baronian guards were somehow able to trace Cecil to Kaipo (maybe it was just chance Rosa was taken in there after contracting desert fever?), and Golbez gained power in Baron without Cecil having met him yet.

Well, maybe one could have a more elaborate discussion on what was going on then and before the game's events began, but feel free to answer however you like as according to this thread.
