Carol IRL
Carol Ann Susi passed away on November 11, 2014, from lung cancer. Her death was recognized in the show’s eighth season, where they made mention that she passed away in her sleep while on a trip to Florida. In the last scene of the episode, we see the TBBT gang toasting Howard’s dear mother before the screen fades to black.
In remembrance of Howard’s mother and the actor behind the voice, Sheldon and Leonard kept a picture of her on the refrigerator. The producers of Young Sheldon used a recording of her voice in an episode. TBBT was just one of many of Carol’s incredible on-screen works.
