Think Guwaru will amount to anything?

The entire thing with Guwaru was essentially a punchline to a setup that was forgotten half a year ago.

 Spoiler

Guwaru was the first of the Black Mage's commanders to be confirmed alive (von leon's existence hadn't been made public yet and the others don't appear until later, timeline-wise), which panicked the entire Maple World into forming the Alliance. As it turns out, although they were right about the commanders still being around, the one who actually raised the initial panic was the one that they didn't need to worry about in the first place.

So basically...a brick joke. Oh well, at least his turning up meant they were slightly more united in their efforts.
