A couple of points here in today's comic, complete with some linky reminders for your convenience:
The people of Barthis were in despair the last time Jacob paid a visit.
If not for Jacob, Luna would be dead.
Unless I'm mistaken, this is the first time since Jacob and Quilt parted ways at the end of The Storm of Souls that they've been face-to-face.
More linky reminders to come as we see why Bumper's death seems to have affected Quilt so profoundly. I think this is the longest we've seen him go without smiling in a long time.
That's all from me for now.
