  We define a new condition on relatively hyperbolic Dehn filling which allows
us to control the behavior of a relatively quasiconvex subgroups which need not
be full. As an application, in combination with a recent result of Cooper and
Futer, we provide a new proof of the virtual fibering of non-compact
finite-volume hyperbolic 3-manifolds, a result first proved by Wise.
Additionally, we explain how the results of [2, Appendix A] can be generalized
to the relative setting to control the relative height of relatively
quasiconvex subgroups under appropriate Dehn fillings.
