\section{Conclusion}
+We have reviewed the Picard--Lefschetz technique for analytically continuing
+integrals and examined its applicability to the analytic continuation of phase
+space integrals over the pure $p$-spin models. The evidence suggests that
+analytic continuation is possible when weight is concentrated in gapped minima,
+who seem to avoid Stokes points, and likely impossible otherwise.
+
+This has implications for the ability to analytically continue other types of
+theories. For instance, \emph{marginal} phases of glasses, spin glasses, and
+other problems are characterized by concentration in pseudogapped minima. Based
+on the considerations of this paper, we suspect that analytic continuation is
+never possible in such a phase, as Stokes points will always proliferate among
+even the lowest minima.
+
+It is possible that a statistical theory of analytic continuation could be
+developed in order to treat these cases, whereby one computes the average or
+typical rate of Stokes points as a function of stationary point properties, and
+treats their proliferation to complex saddles as a structured diffusion
+problem. This would be a very involved calculation, involving counting exact
+classical trajectories with certain boundary conditions, but in principle it
+could be done as in \cite{Ros_2021_Dynamical}. Here the scale of the
+proliferation may save things to a degree, allowing accurate statements to be
+made about its average effects.
