Endgame

Endgame refers mainly to the final episode of iCarly, iGoodbye. There are multiple ways to discuss this: Endgame is basically where the show concluded - romance, character positions, rivalries, etc.

One of the biggest commitments of the iCarly fanbase is the romantic relationships between the three main characters, Carly Shay, Sam Puckett, and Freddie Benson. While it is/was often speculated which of the three would end up together by the two distinct fan groups Creddie and Seddie (and others like Cibby and Cam - there was, after 100 or more episodes, a "sort of" conclusion.

Here's what definitely happened: Apart from the romance, or lack thereof, there were some crucial events and callbacks:
 * Freddie did evoke a response from Sam; asking if she wanted to get back together, causing a moment of anxiety for them both.
 * Freddie did kiss... well, Carly kissed him. However, neither expressed this to their friends or relatives on-screen.
 * Gibby offered to take Carly to the dance and dressed in a nice tuxedo. Carly wanted to hear Gibby's catchphrase one more time for the road.
 * Sam gave Carly her blue remote.
 * Spencer, Carly, Freddie, and Sam all experienced "flashbacks" to iPilot as Carly was leaving.
 * In the end, no one was officially dating.
 * Colonel Shay made his first (and only) on-screen appearance. His appearance is what causes Carly to leave for Italy as he is unable to spend anymore time at Bushwell Plaza.
 * Mrs. Briggs is still unmarried; meaning her affair with Mr. Howard never prospered.
 * Lewbert remained safe and distanced from his wife, Marta Trundel.
 * Sam got herself a motorcycle.
