Family Macduff puts his loyalty to his king and country before his family. He leaves his family and joins Malcolm in England. His wife, Lady Macduff, is angry and upset that he has left them behind.

The London Standard has reported this was due to a mid-show switch-up in the cast, with understudy Gemma Laurie stepping in as Lady Macduff after regular performer Rona Morison lost her voice.
