We never got to see Wes's final scene before leaving, he just disappears & the storyline is left ambiguously up in the air. Why would the writers do that instead of giving a definitive resolution to the storyline? Is it because they wanted to leave the possibilty that Wes really was Jock Ewing after all?
When Miss Ellie says he told me he wasn't Jock it's only after Donna comments did anyone notice the uninvited visitor after being questioned by Clayton? And this is presumably some time later after the event of Bobby's wedding. Why did Miss Ellie only volunteer this information so late in the day & not immediately after seeing Wes? There's something not right here.
As I've said before if Wes wasn't Jock, she should've been furious with him for upsetting her & the family. She would've had Wes escorted off Southfork. But she doesn't do any of that. Instead she get's angry at Clayton for wanting to go after Wes Parmalee. She wants it all over & to forget it all. She doesn't want Clayton going after Wes. Why?
Now as I've said before we never see the exchange between Miss Ellie & Wes. Although she says that he told her that he wasn't Jock, her reaction to Clayton going after Wes indicates otherwise. Clayton threatened to kill him at the Oil Baron's Ball & he made it clear in other confrontations with him that he didn't care if he was Jock or not as he'd grown to love Miss Ellie.
I'm firmly convinced that Wes Parmalee is Jock Ewing & Miss Ellie guessed the truth of this. She sensed there was something between them. If Wes did indeed say he wasn't Jock then he lied in order to protect his family & left so as not to put them through any more pain as they didn't believe who he really was. Maybe Wes held Ellie one last time, kissed her & then said goodbye to her one last time. Wes wasn't a conman, he took off right after Jeremy Wendell said he was gonna stick it to the Ewings. Wes did the only noble thing he left to spare his family any more pain, or rather Jock did.
