The Big Bang Theory Season 12: 10 Things That Must Happen Before It Ends

10. Leonard's Mother Is Proud Of Him

For the time that Leonard Hofstadter has been on our screens, one thing that has ever rarely changed is how ashamed his mother, Beverly, is of him. Despite him being an accomplished experimental physicist, Leonard has never been able to gain the admiration of the woman who gave birth to him, with Beverly giving more praise to his brother and sister, a Harvard law professor and medical researcher respectively.

Given how he acted with Sheldon when he made his scientific breakthrough in the Season 11 finale, Ms Hofstadter could be on her way to handing praise to her son for the first proper time. The more dedicated fans may recall she hugged Leonard once, albeit while under the influence of alcohol. That encounter made Leonard feel incredibly uncomfortable, but considering the amount of times he's mentioned his mum never being proud of him, he would surely be over the moon to get some real praise from her.

Knowing Beverly though, she'll more than likely focus most of her attention on Sheldon.
