When asked to be more specific about the couple that will be getting engaged, he declined to give any further details maintaining that it could happen to any of the couples.
He insinuated that if Leonard became a part of the Koothrappali household, many relationships will be impinged on in an exciting way. He further intimated that Howard has always been interested in being a family man.
“If Sheldon proposes, it would have much bearing because he had always believed that all his affections has been won by science”, Prady asserted.
