Episode 1 of "The Santa Clauses" ends with Santa falling off the roof while delivering presents, just like the first movie begins. If you remember, Scott starts the series as an executive at a toy company who accidentally becomes Santa when the previous Santa falls off his roof while Scott watches from below. Scott follows the instructions on the card in Santa's jacket, requesting he put on the Santa suit to finish delivering the toys, with the promise that the reindeer know what they're doing.
In the first film, Charlie is amped about his dad becoming Santa, but Scott approaches the development with trepidation and disbelief. Even after delivering toys to children, visiting the North Pole, and being magically transported home to Chicago on Christmas morning, Scott tries to convince himself it was just a dream despite Charlie's insistence that it really happened. When Scott begins gaining weight and growing a white beard, his transformation into Santa becomes impossible to ignore.
When Santa's magic fails during "The Santa Clauses" and he falls off the roof, Santa wonders if he is the right man for the job and if this entire career as Santa was one big fluke. Episode 1 lays the groundwork for Santa contemplating retirement before he vanishes like the previous Santa does in the first film.
