Digger/Fridge

Fridge Brilliance:

 * Shadowchild came from the corpse of a white bird. What form does  sometimes take, again? A  ? Just a little something to think about, a possible parallel or connection between Shadowchild and.
 * Read the last panel here -- the skin lizards say that, when people die, their hearts became kingfishers.

Fridge Logic:

 * Where does all that dirt go?
 * In-universe as well: Digger is as surprised by this as we are.

Fridge Horror:

 * It's strongly implied that Sweetgrass-Voice managed to  by stretching himself thin, the same way shadowchild does. It's also implied that   is hundreds, if not thousands, of miles away from Sweetgrass-Voice's  . Think for a moment on how utterly massive Sweetgrass-Voice has to be in order to stretch that far and still retain a perfectly coherent form.
 * The 'stretching' is implied to be more of a metaphysical than physical maneuver. Sweetgrass-Voice says "But now you have come here, where reaching is easier" when they are at the monastery. The barriers between worlds are weak enough that Descending-Helix can manifest, and weak enough that Sweetgrass-Voice can 'stretch' himself there much easier.
