Is Uncle Leo the brother of Morty or Helen? Has this question ever been answered on Seinfeld- I don't think so.
Seinfeld Question.
Fans discuss whether Uncle Leo is Morty or Helen's sibling, with consensus that he is Helen's brother based on an episode involving their father's track winnings and a fifty-dollar debt.
i think he's Helen Seinfeld's Brother
Helen. Leo was supposed to give $50 of his father's winnings to Helen 45(?) years ago. There was a whole episode bout dat.
I believe that Uncle Leo is Helen,s brother. I seem to remember an episode where their Dad had won some money at the track and gave uncle Leo a hundred dollars to split with his sister. Jerry later found out that Uncle Leo had never paid his mother the fifty dollars.
Helen's brother, because in one episode, Jerry discovers through his grandmother that when Helen and Leo were kids, Leo never gave Helen the money she was supposed to received from Leo that he won at the races.
Helen. It was answered during the episode when Leo wants to put Jerry's Nana in the nursing home.
