Guest characters

The guest character is the one which acts only in a few episodes or scenes. Unlike regular characters, the guest ones do not need to be carefully incorporated into the storyline with all its ramifications: they create a piece of drama and then disappear without consequences to the narrative structure, unlike core characters, for which any significant conflict must be traced during a considerable time, which is often seen as an unjustified waste of resources. There may also be a continuing or recurring guest character. Sometimes a guest character may gain popularity and turn into a regular one.
