This was such a creepy episode ๐ญ I do understand why the mom made the decision to not want anyone to know about her death. The fosters care system is a shit show, she was right about people not wanting several siblings. Also a lot of foster parents are just really mean and want the money. A lot of people are heartless like that.
My grandma was a foster parent and she took in a few kids and she had foster parent friends too and she used to tell me stories about how people didn't want to take in siblings and only want to take one kid. Also looking from the kids point of view, the oldest girl was right. I would have fostered them too, but after finding out they buried their mom and pretended to be her, I would have changed my mind on that ๐
