5 Young Sheldon Actors Who Also Played Different Roles on The Big Bang Theory

Among all the characters on “The Big Bang Theory,” Penny unquestionably has the most romantic entanglements. Some of her notable relationships include Kurt (Brian Patrick Wade), Zack (Brian Thomas Smith), and her eventual husband, Leonard. Another significant relationship worth mentioning is with Dr. David “Dave” Underhill, played by Michael Trucco. Dave appears in Season 2, Episode 11, when Leonard inadvertently introduces him to Penny while they are working together on a project at Caltech. Initially, Dave seems like he might be the perfect guy to end Penny’s streak of bad relationships, but it doesn’t take long for her to find out that he’s been dishonest with her and is actually married.

Penny comes to the realization that she was more attracted to the idea of Dave than Dave himself. This situation mirrors an experience in “Young Sheldon,” involving Mary (Zoe Perry). Mary becomes infatuated with the idea of Rusty, a character made up in her imagination and also played by Michael Trucco. In Season 6, Episode 3, Mary occupies her time reading romance novels as she remains estranged from her church. This leads her to believe that she could write a better romance novel herself, so she begins to craft the story of Rusty and her alter-ego, Marie. Similar to Penny, Mary discovers that fantasies can be overrated. Nevertheless, her writing kindles a renewed passion in her relationship with George. Trucco’s appearance on “Young Sheldon” serves as a playful connection to its predecessor and underscores some surprising similarities between Mary and Penny.
