The group had already declared 2 of the Boudreaux children "dark" (from Annie's timeline), and MBP knew about it and (as of 7/26/19) was "taking it well." --MB actually had some level of love for her children which is probably what LD, who had no lasting love for her own, leveraged against MB. If she turned, she'd lose her children. What MB didn't know is, successful in eliminating BB (and cashing in on his life insurance), how quickly LD would have labeled the children as dark, properly insured of course.
7/20/19: Lori Vallow and Chad Daybell speak in the most deplorable terms about Melani Boudreaux’s son, Blake—and indicate he is close to death (source):
Lori: What’s Blake’s percentage??
Lori: He drew three crosses on the wall in his bedroom. We just finished painting over them.
Lori: Like he was marking it for the dark side to find him.
Chad: Blake is at 7. I took my sword of light and sliced his aura vertically in several places. You should be able to now rip and burn it.
Chad: I also decreased his pain tolerance to 1 percent and greatly increased his pain. His desire to depart is at 80 percent.
7/22/19 – 7/23/19: Lori Vallow and Chad Daybell discuss via text an evil spirit named Elroy trying to attack him. She also references the Boudreaux son, Blake, who Lori, Melani, and Chad thought was evil. (He was estimated to be 3 or 4 at this time.) Chad also tells her about other evil spirits they needed to rid the world of (source).
Chad: There are 272 3s left, and none of them have occupied a body before. They are down to their last reserves. I’m glad I caught Elroy. I feel he was aiming to hide out and then get into JJ.
Lori: Good morning missing you. Didn’t sleep much. Need you to check jj. Weird stuff happened in the middle of the night. It’s like they distracted us with Blake.
7/26/19: Lori Vallow and Chad Daybell have a text exchange about JJ, Tylee, and Melani Boudreaux’s (now Pawlowski) older daughter, Brighton (source):
Chad: How are things at home?
Lori: She’s fine. Need you to check JJ. She said he was calm and he watched movies all day which he would never do. Missing you !!”
Chad: Missing you too! It is still JJ. I’m told she is lying about him being calm and watching movies.
Lori: Mel knew. She called me. She felt the real Brighton last night and knew she was different. She was told I didn’t want to tell her. She is taking well and knowing it is part of a big plan. She is amazing!
7/29/19: Chad Daybell and Lori Vallow have a text conversation about Melani Boudreaux’s two middle kids who they all had deemed dark (source):
Chad: One question: Do you want me to cause pain yet to those two 3s you’re riding with?
Lori: Probably hold off on them till we arrive. They will be mistake to deal with. But I’ll text you if they start acting up and we can zap them.
Lori: Miserable not mistake.
Chad: Sounds great. Yes, if they are going to act up, we’ll at least give them a reason to scream.
8/7/19: Lori Vallow sends Chad Daybell a series of text messages where she asks him to pray God will take Tylee, JJ, and the two middle Boudreaux kids because she and Melani were tired of taking care of demons (source):
Lori: I love you. Taking Braxie home now. I’ll check on her.
Lori: She is asleep. She put a bunch of holes in the walls and doors. Definitely had demons helping her. Probably a thousand.
Lori: Mel wants us to come up there tomorrow, but I said next Thursday to Sunday. What do you think?
Lori: We are both so tired of taking care of demons. We are weary. Please ask the Lord to take them.
