The Voting shares storyline was silly. As it has been said, Jock giving Ray and Gary voting shares in a company they did not know anything about and in an industry they knew nothing about. Gary giving his shares was especially stupid since Lucy knows nothing about nothing. It was just a way of getting a laugh at JR's expense.
Jock would not have given voting shares to Lucy, a female but would give them to John Ross, his grandson and heir. And regarding Lucy, if someone gave me shares in a company voting or non voting, the first thing I would do is get to know everything about that company.
Finally, JR taking this lying down seemed silly to me as well. He should have been on the phone to Jock to know why he did this. Not to mention that JR had been at Ewing Oil since he was 15. Very unlikely he would accept Ray, Gary, Bobby, or Lucy deciding his fate in his company.
