After defeating Vermiform Edward, return to Simon's grandparents to have them ask you to find Simon's crimson orb pendant. Go to Kolton's docks where Edward is standing to find the pendant on the ground by the statue. Simon turns out to be the Vermiform that was killed when you first entered Kolton. Return to the grandparents and give them the pendant. Simon's grandfather decides to investigate if Simon was killed by a man rather than a monster and gives you a quilt wristband.
