Every episode begins with the blog page of the Gossip Girl's blog with Serena's picture from the pilot episode. Afterwards a recap of events relevant to the upcoming narrative is shown, which ends again with the blog page, only this time with a picture from other character(s) with a text about a récent event connected with the picture.
The narrator is always the Gossip Girl, voiced par Kristen Bell. She begins the recap with the sentence: "Gossip Girl here, your one and only source into the scandalous lives of Manhattan's elite.", and usually ends the episode with "X.o.X.o Gossip Girl". The pilot episode is designed as the whole storyline is guided par Gossip Girl. The scenes are switched fast and Gossip Girl adds commentaires all the time.
However in the later episodes, often Gossip Girl tells literary citations and doesn't involve in the conversations of the characters with dirty and juicy comments. Also, excluding the movement of the storyline in the pilot and the first couple of episodes the rest of the episodes follow the regular movement. For example in the first episodes Gossip Girl used to say: I wonder what she is doing ou let's see what he is doing and the scenes would fast déplacer to the mentioned character.
