The sudden reemergence of the missing passengers of Flight 828 after five and a half years has raised plenty of questions on Manifest, setting the stage for an overarching mystery that continues to leave those affected dumbfounded.

For the plane's confused passengers, re-adjusting to a world that has essentially moved on has been a challenging road so far, and one made all the more difficult by mysterious voices and strange urges that allude to a potential omnipresent being forcing them into action. And now, things are even more mind-boggling with the appearance of another supernatural force.

In this exclusive sneak peek at Monday's episode, Saanvi (Parveen Kaur) exits the elevator at work and passes by a dark figure that has left dirty footprints on the ground. Turning around, she finds herself face to face with a creepy apparition that looks straight out of a Doctor Who episode. Instead of murdering Saanvi as the BBC series' Weeping Angels have been known to do, however, the figure simply vanishes. The question remains: Why did this apparition appear? And what does it want?
