This morning, while I was lazing around reading instead of doing all the stuff I should be doing, I finally figured out how Jara's hero saves the day... of course at great cost to himself, and by extension at great cost to Jara.  But he heroically saves the day, which was the piece I needed before I could go on with the story.

Which is good news, but of course now the problem is finding the time to implement it.  Always a challenge.
