The fact is, acknowledging her hanging out with Luke on this show dilutes the story this show wants to tell about her carrying Anakin's legacy. She should know that Luke is carrying that legacy as well, but of course the answer's the same - she knows it intellectually, but she still needs to accept it. I get it for the sake of this narrative, but I feel an interesting story could have been told springing off her time with Luke rather than ignoring it. (although if the show finds a way to address this, then I will stand corrected)
