Meet Sam and Quinn aka Barbie and Ken according to Rachel Berry :))
Ryan Murphy said they were too perfect with each other that's why he broke them up in the story. So sad about that :(
Their love story started with the song "Lucky" by Jason Mraz and Colbie Caillat during the Duets episode. Then after that, Sam gave a promise ring to Quinn telling her that he thinks he loves her. They were the ones who sang Time Of My Life during Sectionals!
It's just a sad ending for them because Sam has been cheated on by Quinn. I think she's stupid enough to be going back to Finn like that.Plus, what's more stupid about her is that she even said to Sam, "I wanna be with you." during the 'Comeback' episode but then on the 'Sexy' episode, she made out with Finn. Aw, such a stupid thing to do.
Anyways, I still hope that they will be back with each other once again.
