In the episode where we found out that Kristin shot JR and framed Sue Ellen for the crime, we find out something else that makes Kristin look as dumb as a box of rocks. We were told that Sue Ellen went to Kristin's place with a gun and told her she had the gun because she (Sue Ellen) was going to shoot JR. Kristin handed Sue Ellen a drink to get her to put the gun down to take the drink and then Sue Ellen being drunk, forgot to pick the gun back up and left. Kristin then took the gun to Ewing Oil and shot JR. Why do that and try to frame Sue Ellen instead of just letting Sue Ellen go and shoot JR herself? That way Sue Ellen would have been guilty instead of Kristin. JR was going to get shot either way. If you want someone shot and someone else is willing to do it, why risk a prison term by insisting in doing it yourself?
