A Mercy - Toni Morrison

I have a question about the interpretation of the denouement, of Florens’ denouement.



I interpreted the violence between The Blacksmith, Florens, and Malaik as:


Florens attacked The Blacksmith, lashing out at him and wounding him with his tongs, and then attacked Malaik and killed him. Malaik, taking her place (in her eyes), was the symbolic stand-in for her brother, so she destroys him this time. The Spark Notes for A Mercy, however, state Malaik lived. https://www.litcharts.com/lit/a-mercy ?
