Having been unknowingly possessed by Mary, Eve is on high alert. Matters are made worse by the fact that her memories of recent events are corrupted. Could Eve's actions be down to a sleeper virus, or - as Will suggests - has Mary found some way to cheat death? Eve's investigation is put on hold when Abe embroils her in a family drama. The Watsons have been invaded by their crotchety grandma Gloria, who is irate having discovered Abe's online competition to name his newborn brother. Eve witnesses the Watsons' meltdown as Gloria reveals that she never approved of Maddie and Viv's marriage.
