The circumstances in which Sid is presented in this series correspond largely to the Mirage comic book. In the 2003 TV series, Sid was looking for the buried treasure in the farm because he had to pay back the gambling debt he owed the Purple Dragons. Casey and April selflessly helped to cancel his debt with the Dragons.
Sid changed for the better and returned to the farmhouse as a guest at April and Casey's wedding. Casey's mother explained that she told him about Casey and April's "friends", and that if he told anybody about them, she'd bust his kneecaps. Sid later participated in the general brawl that broke out following the Cyber Shredder and the Foot Clan's attack on the wedding.
