7. Ali's Cameo (Paranormal Activity: The Marked Ones)
After another marked boy, Oscar, kills himself, Oscar's brother Arturo tells Hector and Marisol that Oscar had been talking to Ali Rey, Daniel's daughter from the second movie. The pair arrange to meet up with her, where she explains that the witch coven known as the "Midwives" want the demon to consume Jesse. Given that The Marked Ones is the "black sheep" of the series in terms of being a spin-off, seeing one of the series' few surviving protagonists make an appearance was very much welcome and totally unexpected.
