“I’m trying to figure out how something you’ve never seen before managed to get into your suitcase.”
So the plan, as I understand it, is as follows: sinister sorceress Angelique Collins and her housekeeper pal Hoffman will break up the marriage between Angelique’s one-time husband Quentin and his now-time wife Maggie, by making Maggie paranoid and hysterical, so that Quentin won’t be able to stand living with her. They’ll accomplish this by doing super suspicious things right in front of Maggie, and then acting weird and petulant about it, so that she knows they’re doing something suspicious, and thereby lulling her into a false sense of insecurity. It’s the perfect plan; she’ll never see it coming.
