  We investigate the conditions for obtaining four-dimensional massless spin-2
states in the spectrum of fluctuations around an asymptotically $AdS_5$
solution of Einstein-Dilaton gravity. We find it is only possible to have
normalizable massless spin-2 modes if the space-time terminates at some IR
point in the extra dimension, far from the UV AdS boundary, and if suitable
boundary conditions are imposed at the ``end of space.'' In some of these cases
the 4D spectrum consists only of a massless spin-2 graviton, with no additional
massless or light scalar or vector modes. These spin-2 modes have a profile
wave-function peaked in the interior of the 5D bulk space-time. Under the
holographic duality, they may be sometimes interpreted as arising purely from
the IR dynamics of a strongly coupled QFT living on the AdS boundary.
