 Question: has camelot been sold to a canadian company Context: The group keeps searching for Sophia but is unsuccessful. In the episode ``Cherokee Rose'', Carl's injuries ultimately lead the whole group onto Hershel Greene's farm, where they settle. They continue their search, but still nothing seems to turn up. In the episode ``Chupacabra'', the only thing that comes to light is Sophia's doll, which had been discovered by a member of the group named Daryl Dixon. Daryl goes on several searches for Sophia, being one of the most devoted members of the group in looking towards recovering her. He and Carol bond greatly because of his efforts. In the mid-season finale ``Pretty Much Dead Already'', Glenn tells the group that he discovered that Hershel has been keeping a group of walkers, consisting largely of his family and neighbors, in his barn, as he had believed them to be sick but nonetheless curable patients. Shane goes against Rick's orders, opens the barn, and (along with the rest of the group) shoots all the walkers that stumble out. Just as things seem to be over and done with, one more walker stumbles out of the barn - Sophia, who had been bitten while in the woods. (She had then been found by Otis, who put her zombified form in the barn before his death.) Knowing what must be done, Rick steps forward and shoots her, putting her out of her misery. In the mid-season premiere ``Nebraska'', she is buried in a funeral ceremony, alongside Hershel's second wife Annette and stepson Shawn (who were also kept in his barn as walkers). Carol does not attend the funeral because her daughter ``died a long time ago''.
 Question: the walking dead do they ever find sophia Context: During the 19th century many of the smaller German and Italian states were ruled by Dukes or Grand Dukes. But at present, with the exception of the Grand Duchy of Luxembourg, there are no dukes ruling as monarchs. Duke remains the highest hereditary title (aside from titles borne by the reigning or formerly reigning dynasty) in Portugal (though now a republic), Spain, and the United Kingdom. In Sweden, members of the Royal Family are given a personal dukedom at birth. The Pope, as a temporal sovereign, has also, though rarely, granted the title of Duke or Duchess to persons for ``services'' to the Holy See. In some realms the relative status of ``duke'' and ``prince'', as titles borne by the nobility rather than by members of reigning dynasties, varied--e.g., in Italy and the Netherlands.
