FWIW, OW has been described to me as meek, mild, and quiet. My intuition is suggesting that her self-esteem is not so great. I hate to sound like a witch, but yes, I think she'll crack.
There are some toys here that belong to her daughter. If there's a sudden push to get those back to her, I'll know something is up. There's also a note listing the toys and a phone number on H's dresser - plain view, not snooping. I don't know if it's new or not as there's a lot of stuff (receipts, tags, groc. lists) on that dresser. At any rate, it will bear watching.
The trouble with having an open mind is that people put things in it.
