Ryan Phuong and Iain Armitage in Young Sheldon (2017) Rockets, Communists, and the Dewey Decimal System
S1E2
When Mary Cooper sees Sheldon eating alone in the cafeteria, she is worried with the situation. Sheldon loves to be alone to think, but decides to please his beloved mother and borrows a book from the school library to learn how to make friends. The system fails but he meets the Vietnamese Tam that also wants to make friends and loves also rockets' design.
*In The Big Bang Theory (2007), S01E04, The Luminous Fish Effect (2007), Sheldon makes reference to when he was a child and got into trouble with the FBI after purchasing uranium to use for generating electricity, a story also told in S08E23, The Maternal Combustion (2015). That event is depicted here.
