 After a small perturbation, we may assume that $q$ is simultaneously transverse to all the splittings in $P$, and
 (by Axiom \ref{axiom:splittings}) that $c$ splits along $q$.
 We can now choose, for each splitting $p$ in $P$, a common refinement $p'$ of $p$ and $q$.
-This constitutes the middle part of $\vcone(P)$.
+This constitutes the middle part ($P\times \{0\}$ above) of $\vcone(P)$.
