H is for Hunted

Will creates an Astral Drop of herself so she can get her chores done. Nerissa then turns it into an Altermere, an exact duplicate of Will, including her feelings, memories, and powers. While Will is trying to find it, Nerissa convinces it to take Will's place, and a battle erupts. The other girls try to help, but they can't tell which Will is real. The Altermere becomes good and is almost destroyed by Nerissa but Will absorbs it into herself in order to let its feelings, memories and emotions "live inside Will's mind." In a second storyline, Will is forced by her mother to do laundry.
