Meryl of course plays mom to the late Perry Wright, who was portrayed by Alexander Skarsgård in the first season. She comes to Monterey concerned for the well-being of her twin grandsons. Kidman's character, Celeste, of course plays their mom.
I have to admit that Meryl's look here is dowdier than I had expected. I thought she'd maybe look super duper posh. It's hard to tell from one photo, though. I maintain that Meryl's character will be an abused person as well, as that behavior is almost always learned. Maybe Perry's father was the same way toward Mary Louise as Perry was to Celeste? Great character to watch Meryl unfold!
