Elena is an idiot, for real. The Ewings didn't do shit to her. J.R. is the one that screwed over Poor Dead Papi and he's DEAD. She wants Bobby, John Ross and Christopher to pay, when none of them had anything to do with it? John Ross and Christopher would have been kids at the time and Bobby is the Most Decent Man on Earth. Hell, I'm not even sure J.R. is guilty. Not that the old scoundrel (I say that with love) was above that sort of thing, but c'mon, taking Cliff's word for it? He could have faked all that so-called proof. It's not as if he has a decades-spanning feud with the Ewings or anything. C'mon, Elena, think!
None of this would really be a problem if the show would go ahead and make Elena a villain. But that's not going to happen. Poor Elena, she's been lied to, manipulated and used. Maybe she's a little misguided, but she would never do anything really bad! Even covering for her bombmaker, baby-murdering brother was all about family loyalty, which those evil, evil Ewings wouldn't understand, what with them trying to prosecute her for covering for a fugitive and firing her mother and holding a grudge...oh, wait.
