The Big Bang Theory: 10 Major Predictions For Season 12

10. Penny's Last Name Revealed

Out of the main female characters in the show, there's Bernadette Rostenkowski, Amy Farrah Fowler, and Penny... just Penny. She was the third character we were introduced to following Leonard and Sheldon, but we've never uncovered her last name. Not even a hint has been given.

Did she take Leonard's surname when they married? Has she kept her family name this whole time? Who knows. Some of Penny's family members have appeared on the show in previous years, but we didn't ever uncover the mystery surname.

It seems a bit strange that she's been a major focus on the show since the very beginning, and we're yet to know what her surname is. Considering we know the last names of minor characters like Stuart and Bert, you'd think Penny's full name would've been revealed by this point.

Season 12 simply can't come to an end without Penny's last name being revealed to viewers. It obviously wouldn't be that much of a big thing - after all, it's only the unveiling of a surname. But it would be great for us viewers to finally get some closure on Penny's last name. Otherwise, there will be an uproar of anarchy on the streets of Pasadena.
