  Using our previous results for the configurational entropy of a stripe glass
as well as a variational result for the bare surface tension of entropic
droplets we show that there is no disagreement between the numerical
simulations of Grousson et al. and our theory. The claim that our theory
disagrees with numerical simulations is based on the assumption that the
surface tension is independent of the frustration parameter Q of the model.
However, we show in this Reply that it varies strongly with Q and that the
resulting Q-dependence of the kinetic fragility agrees with the one obtained by
Grousson et al. We believe that this answers the questions raised in the
Comment by Grousson et al.
