The next morning, after the Specials leave, Tally and David leave the cave to check out the damage. Luckily, David still has a hoverboard, so they ride down to the Smoke.
Or at least the smoking ruins of the Smoke. The Specials burned down everything, including the library and all the books/magazines in it. (Remember, this is a tragedy, not a comedy.)
As David explains, Dr. Cable burned the library because she doesn't want people to have the chance to see what life was like before.
But there's also a pile of shoes that the Smokies left for Tally. Apparently Croy saw her escape, so all the Smokies left their shoes so she could find a pair that fits her (since he saw her shoeless in the rabbit pen).
Then David and Tally find the Boss (murdered, major bummer) and his hidden cache of magazines.
And then Tally and David go off to David's parents' house. Keep your fingers crossed that no one else is murdered.
