Will puts on the sunglasses and looks at the woman. She glows. And "the outline of her body wiggled and squirmed like a bagful of angry cats" (9.5).
The woman enters the airplane lavatory, and soon water seeps out under the door.
Instead of running away from the nasty bathroom, Will heads toward it, where he sees the woman dissolve into a wriggling mass and flush herself down the toilet.
That is the nicest thing we've ever seen in an airplane bathroom.
Back in his seat, Will is told by Dave that the woman was a "Carrier" (9.23).
Speaking of Carriers, there are now monsters on the wing of the plane. Will, get ready to do your best Shatner.
Dave teleports onto the wing and kills all the gremlins.
As Will watches, he sees the reflection of a girl's face looking back at him. She telepathically asks him a question: "Are you Awake?" (9.58). How did her voice capitalize the A?
