+    An example of a Stokes point. (Left) The collection of thimbles necessary
+    to progress around from left to right, highlighted in a darker color, is
+    the same as it was in Fig.~\ref{fig:thimble.homology}. (Center) The thimble
+    $\mathcal J_\blacklozenge$ intersects the stationary point $\blacktriangle$
+    and its thimble, leading to a situation where the contour is not easily
+    defined using thimbles. This is a Stokes point. (Right) The Stokes point
+    has passed, and the collection of thimbles necessary to produce the path
+    has changed: now $\mathcal J_\blacktriangle$ must be included. Notice that
+    in this figure, because of the symmetry of the pure models, the thimble
+    $\mathcal J_\blacksquare$ also experiences a Stokes point, but this does
+    not result in a change to the path involving that thimble.

 The prevalence (or not) of Stokes points in a given continuation, and whether
 those that do appear affect the weights of critical points of interest, is a
 concern for the analytic continuation of theories. If they do not occur or
