Weird and mysterious things begin to happen when Leonard suddenly gets invited to New York City to give a speech to grad students at the University of New York which ultimately leads to him meeting the 4 heroes in green after a sudden Kraang attack. I don’t own both shows, all credit goes to the creators.

Sheldon and Amy’s relationship gets reevaluated when the gang suddenly meets a 31 year old woman who just happens to be a theoretical physicist just like Sheldon and feelings start to emerge. I don’t own the Big Bang Theory but I do own Dr. Leo Fordyce. Sheldon/Leo pairing :)
