I don't have the slightest doubt you're right. Almost immediately after LP remarked that Casey liked Rob Dick? (young bounty hunter), Cindy engaged in an inappropriately long and affectionate hugging scene with him at JBP while looking straight at the cameras throughout it.
Far worse and more telling than that episode was Cindy's jealous reaction at the jail both times that George opened a conversation with Casey with an especially "warm" remark. The first time was when he said "Hi, gorgeous" (or was it "Hi, beautiful"?) The next time was when he opened with "I love you." On both those occassions--and NO others--Cindy immediately leaned waaayyy back in her chair so she could snuggle her head against his chest but she was looking straight at Casey in the monitor when she did it.
To me, this is evidence of yet another kind of serious malfunction in that distorted mother-daughter relationship. IMO.
