"He's returned from the dead. The good news? They didn't kill him. The bad news? He wants revenge," states next week's promo for NBC's "Days of our Lives," which revealed on the Friday, January 24 episode that Nick Fallon (Blake Berris) didn't die after Gabi (Camila Banus) knocked him over the head with a rock and subsequently shoved him into the river with the aide of Sami (Alison Sweeney) and Kate (Lauren Koslow).
