most likely guesses-mason, brett, bretts sister, sydney, jackson, issac, cora, ethan, greenberg

although no.1 could probably be mason cause he was around the area where the beast was, corey seemed to have some sort of weird feeling around him last episode and it would be some symbolic thing of liam vs his best friend

but dont be suprised if theo was wrong and its an adult

or it could be someone back from the dead

or possibly someone the beast was in the same room with but used them as an illusion(HIGHLY doubt this, im just saying its possible)
