  • Hitherto

    I loved this show and still like it, but the fact the “hitherto, noice has become so frequent that it bothers me and then used in the Cornell 7 case in such a disgusting part, I hate that you did that. It’s not “noice.” I’ve been absolutely hating that you do that so often, so now it’s just so distasteful, taking an entirely used joke and putting it after talking about a woman who had been drugged “noice.” Come up with something new. The way you placed that wasn’t levity. It was gross.

EP203: Mica Miller: The Pastor's Prisoner
Q: How did JP describe Mica's mental health diagnosis timeline in public statements after her death?
