He's an explanation of what happened to Crono. This comic and the next one with this group of heroes are both very "explain-y". A lot happened that needed to be explained, just in case it was hard to follow.

This is the issue with doing comics in a set amount of time. I have to cram a lot in, and then sometimes explain things if I moved too fast.

As in, I probably moved too fast.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
