  In this paper we show that there is a breakdown of scattering between the
event horizon (or the Cauchy horizon) and an intermediate Cauchy hypersurface
in the dynamic interior of a Reissner-Nordstr\"om-like black hole. More
precisely, we show that the trace operators and their analytic counterparts,
the inverse wave operators, do not have bounded inverses, even though these
operators themselves are bounded. This result holds for the natural energy
given by the energy-momentum tensor of the wave equation using the timelike
vector field of the Regge-Wheeler variable, which asymptotically becomes normal
to the horizons. The behaviour of solutions at low spatial-frequencies and
their behaviour at high angular momenta are the only obstructions causing this
breakdown of scattering. The breakdown follows from an analysis of a
$1+1$-dimensional wave equation with exponentially decaying potential which we
treat for general potentials, and we show that the breakdown is generic.
