How Carol Ann Susi Has Been In Every ‘Big Bang Theory’ Episode Since She Died

Thursday’s episode of The Big Bang Theory, called “The Comic Book Store Regeneration,” incorporated the loss of a special cast member: Carol Ann Susi. Susi played the voice of Mrs. Wolowitz, Howard’s mother. The actress died of cancer in November. Show producers at the time released a statement that said in part, “In addition to her talent, Carol Ann was a constant source of joy and kindness to all.”

While it was known for some time that Susi’s death would have an impact on The Big Bang Theory, the precise plot was not revealed until this evening. Howard rejoins the group after a phone call and informs everyone that his mother took a nap and simply never woke up. Later, the entire cast except Simon Helberg and Melissa Rauch, who play Howard and his wife Bernadette, toasted Mrs. Wolowitz.
