The River of Forgetfulness Picture
I guess this would take place after the end of the comic. The Doppelganger, being as crafty and ingenious as he is, escapes from his prison and ventures back to where he originated from. Since he's not a normal Doppelganger he never came from the Village of Doubles. This Jacob came from an underground world with a river similar to the the River of Lethe from Greek mythology which the strange blue flowers originated from as well. I guess the thought must of stayed in the back of my mind because in Greek mythology the God Hypnos lives by that river.
