I'm just watching season 2 and Kristen's mom is the worst. I understand her determination to do the exact thing to put her family in danger is a necessary plot device but DAMN!? After Leland explicitly tells her his true motives while calling off the wedding you'd think she'd steer clear.
I'm not much further than you are at the time of your posting, but I'm kind of getting the impression that Cheryl knows Leland's nature and knows her family is in exactly in his path.
I could be wrong, but what if she is involved in some aspect of the conspiracy?
I'm also very annoyed at Cheryl's behavior. I thought she would go back to being the way she was in Season 1, a good, loving mother/grandmother but that's not the way she's acting since Leland broke up with her. I don't understand what ulterior motives she might have. Perhaps she's under some demon's spell. Hopefully we'll find out soon.
Edited to say that I've seen a few more episodes and Cheryl is definitely just as evil - if not worse - than Leland! I think when she was seeing him, she liked the fact that he was evil and even though they broke up, she's obviously continuing that behavior. She's deeply enmeshed in demonic worship. I don't think she's even trying to protect her grandchildren anymore. She did tell Leland not to go near them, however, I think she's actually planning on recruiting them into her circle of evil doers which is part of the reason she's sending Andy away to Nepal. Her behavior is just ridiculous.
Edited again to say that I'm now into season 3 and I'm so done with Cheryl! Her behavior is atrocious and now she's grooming her granddaughter to be the head of some evil "family". Not to mention what she's doing to Andy! I wouldn't be unhappy at all if they decided to take her character off of the show!
I don't know. She strikes me as an older woman who is desperately trying to hold on to the last semblance of good looks she has left, trying to date younger men regardless of how attractive they are, and just needs a man of some sort in her life. She's clearly not a "leader" of any demonic conspiracy because she randomly met Leland, but she's a joiner because she wants to feel young and important. The fact that she's "tough" makes it interesting because she can slap Leland, but she always gives in to him and makes the wrong choice.
