Finally caught up! I'm wondering if LH is staying with her MIL because the two are on the same track... defend JRH. Perhaps her welcome in her own mother's home would be different. I still remember that her Mom couldn't understand why she wasn't upset over the death.
I think you're right. IMO her MIL is probably telling LH what she WANTS to hear - feeding the fantasies she might still have that RH was innocent or that this was "God's will". Whereas her Mom (from what we know about the phone call between them earlier) would tell her what she NEEDS to hear, and give her a dose of reality she is probably not ready for. I can only hope this will change as time goes on. Denial is a very strong emotion at first.
