Reading police report about Lori's wallet, clearly she managed to convince the cop that Charles was the one with the problem, and not Lori. Ironic that she would accuse Charles of cheating, when Charles believed she was the one cheating on him with Chad (and I am assuming with a good reason). And then she managed to convince mental health professionals she was fine. She certainly didn't go around like a raving lunatic. Shared religious beliefs don't usually qualify as delusions.
