Before Steven Yeun skyrocketed to fame for his portrayal of Glenn Rhee in AMC’s The Walking Dead, he played a supporting role in the sitcom The Big Bang Theory. 

In an episode titled, “The Staircase Implementation,” Yeun plays Sheldon Cooper’s former roommate, Sebastian. He is seen leaving the elevator and advising Leonard, Sheldon’s new prospective roommate, to “run fast and far.”

Although the scene is brief, Yeun showcases his comedic chops and solid acting. It’s hard to believe that it’s already been almost five years since he joined the The Walking Dead cast.

Since the horror drama’s first season, Yeun’s acting career has flourished by tackling new projects, such as voicing the character Wan for the animated series Legend of Korra, executive producing and starring in the forthcoming film The Aquariums of Pyongyang and acting in a comedy web series with 2NE1’s Dara.
