When in control of Lily after cutting off the gnomes head, go back into the house and grab the teddy from the father's science room in the house. Then go out back to the shed where the teleporter is and place the teddy in the chamber. Then grab paper from the pile of paper near the map on the wall. Use the paper on Dougal, so that lily leaves a note. Finally jump in the chamber, and she will be teleported.
