Just a little update for those who still care:
Part 5 of this story should be in Happy's inbox, waiting to be proofread, as we speak. I've got part 6 partly written and part 7 outlined in detail, so I think it's safe to say that the train is moving again.
I'll probably hold off on posting part 5 until I get part 6 out to Happy, though. It can never hurt to have a bit of a buffer, as the past two weeks have shown me, and I wouldn't want to leave you guys hanging for this long again.
But: stay tuned, there's more to come!
