Dan Schneider, the creator of i Carly, had put out many hints that Sam and Freddie may end up together (even some of the i Carly cast members have hinted on this).
In some of his shows, he has paired up the most argumentative characters, such as Logan and Quinn (Zoey 101), Jade and Beck (Victorious), Josh and Mindy (Drake & Josh), and Gary and Tina (What I Like About You).
This pairing mainly rivals Creddie (C/arly and F/reddie), Cam (C/arly and S/am), Sibby (S/am and G/ibby), and Spam (Spencer and S/am) "Seddie" is first mentioned on the show in i Start a Fanwar when Carly is video-chatting with Adam.
(Note: in the episode the followers of the ship were called "Seddies", when in reality they are more popularly known as "Seddiers").
is the romantic pairing between Sam Puckett and Freddie Benson (S/am and Fr/eddie).
It's the most popular and the most supported ship on the show.
In i Date Sam & Freddie, Sam and Freddie go on a date in a purple booth. It is because of it's color (purple) which happens to be the Seddie color. This is because this is where Sam and Freddie had their first kiss and the official Seddie song "Running Away" is playing while they had their kiss in i Kiss.
