Kamina died I kept expecting him to pop up out of nowhere at some crucial moment with some convoluted explanation as to how he managed to survive. Even though he was a totally awesome character, it made me happy when that didn't happen. The only thing I didn't really like about that show was Simon's ending... the rest of the survivors seemed to lead pretty happy lives, but in his case his girlfriend dies and he becomes a hobo... like... why???
... Neither of those things advanced the plot at all, it was just cruel.
