In the rewall proposal, it is assumed that the rewall lies near the event horizon and should not be observable except by infalling observers, who are presumably terminated at the rewall. We study the location of the rewall, assuming that it is determined by the spacetime evolution up to that time under thermal mass loss of Hawking radiation. We show that later quantum uctuations of the Hawking emission rate can cause the "teleological" event horizon to have migrated to the inside of the rewall location, rendering the rewall naked. In principle, the rewall can be arbitrarily far outside the horizon. This casts doubt about the notion that rewalls are the "most conservative" solution to the information loss paradox.
