Ray Mickshaw/FX Igby Rigney as Bret and Hayes Warner as Debbie Schaffer in The Shards. Upstairs, Debbie’s mother Liz guards her secrets behind a mirrored closet door, and both women sit at "giant vanity mirrors with their lights," a design choice Smith notes is important “to be able to reflect back what they’re seeing.” Like Debbie's house, the downstairs is a practical location, but Bret's bedroom and bathroom were constructed on a soundstage.
