Ship Sinking is an event that seems to kill any reasonable chance of a romantic relationship occurring between two characters in the canon of the work. Though many producers and writers are aware of Shipping in their respective fandoms, that doesn't necessarily mean they like it. It may be because of the actions of the fans if they get too rowdy about it , or they just don't like the pairing involved, have intended the pairing to die for dramatic effect, or have simply decided on an alternative set of partners for those characters. Whatever the reason, the creator loads torpedoes to send the ship to Davy Jones' Locker. Basically, the canon has sunk the ship.
