Young Sheldon season 2, episode 6, "Seven Deadly Sins and a Small Carl Sagan," mostly focused on Georgie's attempts to woo Veronica, a rebellious girl that Sheldon was tutoring. As Mary worried about a local Hell House and its depiction of the seven deadly sins, Georgie worried that his romantic prospects would be put off by the attraction's depiction of lust. While Young Sheldon season 2's sweetest moments kept the show's connection to The Big Bang Theory alive, "Seven Deadly Sins and a Small Carl Sagan" ignored Sheldon almost entirely. His role in the episode was reduced to a gag referenced in the title.
As Georgie tried to woo Veronica and Mary tried to discourage local teens from pursuing a life of vices, Sheldon went trick-or-treating with his sister Missy. Few of his neighbors recognized his costume since Sheldon was dressed as one of his idols, Carl Sagan. However, he was finally given some credit in the episode's ending, leaving Sheldon overjoyed while Georgie was annoyed with his mother for inadvertently ruining his date with Veronica. While Jim Parsons' older Sheldon does narrate "Seven Deadly Sins and a Small Carl Sagan," the outing still felt like it had little to do with Sheldon thanks to Georgie and Mary's plots.
Like Sheldon rebelliously visiting a comic con in season 5, episode, 12, "A Pink Cadillac and a Glorious Tribal Dance," Halloween episodes are a great chance for the show to ground the character's future love of cosplay. Sheldon had some hilarious Halloween misadventures in The Big Bang Theory, from dressing as Howard to attending Penny's party dressed as "The Doppler Effect." However, viewers get to see very little of where the character's love for the holiday began. Since Young Sheldon focused on Sheldon's family over the character himself, viewers never got to see the many childhood Halloween adventures treasured by The Big Bang Theory's hero.
