I found him to be a pretty interesting character, although all his boss battles were ridiculously easy for someone who is supposed to be Squall’s rival. Even his friends were more of a challenge than he was.
His conclusion didn’t make much sense to me, though. Last time we saw him, he was completely obsessed with his dream, and would do absolutely anything to accomplish it. Then, all of the sudden in the ending, he completely abandoned it, and is instead fishing happily with his friends. Did he suddenly go “Oh well, my sorceress was destroyed. Might as well be nice.” or something?
