  We analyse the quantum corrected geometry and radiation in the scattering of
extremal black holes by low-energy neutral matter. We point out the fact that
the correlators of local observables inside the horizon are the same as those
of the vacuum. Outside the horizon the correlators at late times are much
bigger than those of the (thermal) case obtained neglecting the backreaction.
This suggests that the corrected Hawking radiation could be compatible with
unitarity.
