Will There Be Babies In Tbbt? in The Show Posted January 22, 2013 I can see the series finale being about whether or not Penny is pregnant. The tag at the end of the episode (and series) has Penny telling Leonard she is pregnant. And the final words of the series are from Leonard telling Penny: "Our babies will be smart and beautiful". Blackout. And Sheldon saying "and real". Blackout.
