But now that I've had a couple of days to recover from the end-of-term grading marathon, I have been able to put a few minutes into redrawing Ipthorin in one panel, then a couple of hours into inking the page. It's not the best cartooning I've ever done, but it is finished (I think), which is what matters.
Please, I beg of you, click on this image to see how our story ends.

I invite you to notice that I have not merely satisfied Jesse's remaining two constraints—as long as you count the middle of the second tier as a panel, it's the third silent panel in a row; the third panel on that row is mostly swiped from Jesse's recent and awesome Bluefuzz minicomic. Not merely, indeed, for I have also chosen two constraints from each of the preceding four sets of constraints and nodded to these in individual panels: the Corrigan and the Reverse Corrigan; the shop-sign and the Passion of Joan of Arc; the Ditko and the Segar (also a little nod to the J. Chris Campbell in the transition to the last panel); a borderless panel and a reference to Duchamp; even (why not) a panel of pure silhouette. You can see signs of me planning this stunt on one of the thumbnail pages I posted back in November. I'm surprised no one commented on that.
We're planning to leave the whole story up on the website for a little bit longer, but we'll pull most of it down when we start coloring the pages and printing them as postcards. When that happens, you'll have the option to buy a copy of the story, either all at once in a single envelope, or serialized to you (or the recipient of your choice) in the mail one page per week.
Meanwhile, please enjoy it in black and white for free, while it's here. I encourage you to use the comments section to discuss overarching themes in the story. For example: what view does this story take of potentiality and the realization of a single potential? What does that imply about the authors' apparent unwillingness to "grow up"?
