Derek is about to shoot Tim just as Tim bursts out of the water and pulls Derek into the vat, holding his head under water. Tim escapes into the main power plant. Tess tells Derek that Tim will go to Meg's to warn her. Meanwhile, Meg has returned home to Surf Central, followed by Sara and Casey, who are concerned for her and want her to spend the evening with them. A blackout strikes Surf Central and other parts of Sunset Beach and the house is plunged into darkness. Casey and Sara leave to pick up take-out; Meg's alone and is thinking of Ben when Tim arrives. Tim manages to get inside, and is heading for the kitchen when, all of a sudden, Derek appears behind him in the darkness, using a metal cable as a garrote. But at that same moment. (thetvdb.com)
