Five names Penny will never wear, and the one that she can finally, proudly, call hers.
And then, one day, Amy and Sheldon walked through their door and she spotted the engagement ring on her Bestie’s finger. After obligatory congratulations, Leonard asked Amy if she’d take Sheldon’s name, and his best friend said that she wouldn’t, for he loved saying “Amy Farrah Fowler” way too much.
Penny remembers thinking “Why?”
Why wouldn’t Amy take the name of the man she loved? Why wouldn’t she be proud to be Mrs Cooper? Why wouldn’t she want to tell the world they belonged to each other?
And then a nagging voice at the back of her mind had asked her “Why won’t you?”
"The ball is still in her court," Galecki said. "The last couple of seasons have really been about her emotional inabilities. It’s made that character of Penny a well-rounded one, and you’d assume it would always be Leonard’s fault, but he’s been a pretty good partner to her."
