Grayson pulls Kate from the flames first, leaving Zinnia trapped inside with injuries only he has the skill to treat. Kate tells him Zinnia terminated their pregnancy, and he believes her long enough to file for divorce. By the time a colleague tells him Zinnia is dead, he is already driving home to a house with nobody in it.
Zinnia's mother goes looking for answers and finds her daughter's kidney donor record, a detail that points somewhere Kate never expected. Zen follows the paperwork and proves Kate set the fire herself. Grayson learns the full shape of what he threw away, and the accident that follows takes the last thing he had left to lose.
