Ben (Josh Dallas) forms an uneasy alliance with a college student from Flight 828 whose callings either exposed a violent crime or helped him commit one himself in a new episode called "Grounded." Saanvi (Parveen Kaur) continues pushing her research into the Death Date, while Grace (Athena Karkanis) is startled to find out something about her pregnancy. Elsewhere, Olive (Luna Blaise) finds a kindred spirit. Garrett Wareing and Ellen Tamaki guest star.
