Here's Where Everyone Ends Up on Revenge

Emily/Amanda survives being shot by Victoria. It's possible doctors transplanted Victoria's heart into her chest, but that also may be just a bad dream Emily/Amanda has. She reconciles with Jack just in time for him to be stabbed by White Gold. He lives and asks David for Emily/Amanda's hand in marriage. (This is when David is still alive, obviously.) They get married, Emily/Amanda gives Jack a puppy that looks just like his old dog, Sammy, and the two plan to set sail across the world.
