In Lucifer, Season 2 Episode 09 ("Homewrecker") Lucifer's mother is very different, and you can see a big change in personality. Previously, she was acting very sweet, like a devoted mother, and now based on her facial expression, she is just the opposite. I don't know, I feel something evil about her demeanor.
I'm also unclear why she is getting involved with Dan? For him it seems like just an escape from his failed relationship with Chloe, but what is Charlotte getting out of it? What are her plans?
With all the recent mixing up of what it means to be an angel or demon, and now Lucifer's mother, I'm getting very confused. What's Charlotte's behavior all about?
