This is seen throughout the episode through interactions with Jolene (Moses Ingram), who gives Beth the money to get to Russia, Townes (Jacob Fortune-Lloyd), who surprises her at the tournament, and Benny (Thomas Brodie-Sangster) and Harry (Harry Melling), who assemble a team to help her prepare for the final match.
Chess is a solitary game, but that doesn’t mean the lives of the chess greats have to be spent all alone.
No matter what she did to these people and how poorly she may have treated them, they all show what it means to be family.
That’s very much the case for Beth in the final episode of The Queen’s Gambit as she realizes that she is not alone in the world even if both mother figures in her life are dead and her father didn’t want anything to do with her.
