Serena Joy is the Commander's wife who once worked as an activist of anti-feminism. This character has a name of Serena Joy because it was her stage pseudonym. She was a Gospel star and used to be a motivational speaker. She remembers that time of her youth when she performed as a singer at Gosper TV shows.
Now she is not famous at all. Serena Joy spends most of her free time at home knitting, but this activity is not her strength. In the world of Gilead, she has the highest social positions, although she is miserable. She knows about her husband's affair with Offred, and she blames the narrator for this.
