Where Is Tam, Sheldon’s First Friend, In The Big Bang Theory?

Young Sheldon season 1 introduces Sheldon’s very first friend, Tam, who wasn’t in The Big Bang Theory. Sheldon was so close to the Pasadena gang that he was almost like family. Despite his quirks and oddities, not to mention being inherently difficult, Leonard, Penny and the rest of the group were mostly patient and understanding of the socially inept genius. The Big Bang Theory made it seem like Sheldon didn’t have any social group before he met the Pasadena gang. This made their bond so much more special. However, this apparently isn’t the case, as seen in Young Sheldon season 1.
