Poor Willie, stuck with a hideous carpentry task. He tries to offer Maggie a way out, but she refuses.
Sarah's scene with Maggie is wonderful, and her scene with Sam is even better.
The last act is still heart-stopping even after several viewings! Wonderful cross-cutting between Maggie desperately working out Sarah's riddle and escaping and Barnabas's awakening and pursuit. (But why doesn't she close the panel after her--especially given that Sarah told her that Barn doesn't know about it?)
In the last scene, JF once again uses his wonderful voice to terrifying effect!
