Cuoco also added that a lot of questions will be answered just as the season starts, but stopped short of revealing any major surprise and said “I wish I knew more things... they don’t tell us anything.”

In the season 8 finale, fans got to see Leonard and Penny drive to Las Vegas to get married, though there seemed to be a confusion on Penny’s part as she was starting to rethink the plans for marriage. However, Cuoco teasing that “all her dreams came true” hints at the couple’s impending nuptials.

Meanwhile, the all-new season will see the return of Penny’s father, Wyatt (Keith Carradine) in the third episode, according to Entertainment Weekly.

This will be his second appearance in the show, following the episode titled “The Boyfriend Complexity.” Rumor has it that his return has to do with Penny looking for family support at the time of her wedding.

In other news, Sheldon’s (Jim Parsons) mother, Mary Cooper (Laurie Metcalf) will also be returning to the series in the premiere episode, possibly to help Sheldon in getting back Amy (Mayim Bialik), after the heart breaking move from Amy in the last season’s finale.
