It is argued that a unitarity-violating but weakly [ital CPT] invariant superscattering matrix exists for leading-order large-[ital N] dilaton gravity, if and only if one includes in the Hilbert space Planckian thunderpop'' excitations which create white holes. [ital CPT] apparently cannot be realized in a low-energy effective theory in which such states have been integrated out. Rules for computing leading-large-[ital N] superscattering are described in terms of quantum field theory on a single multiply connected spacetime obtained by sewing the future (past) horizons of the original spacetime with the past (future) horizons of its [ital CPT] conjugate. Some difficulties which may arise in going beyond leading order in 1/[ital N] are briefly discussed.
