     \item<1-> Suppose $p$ were the largest prime number.
     \item<2-> Let $q$ be the product of the first $p$ numbers.
     \item<3-> Then $q + 1$ is not divisible by any of them.
-    \item<1-> Thus $q + 1$ is also prime and greater than $p$.\qedhere
+    \item<1-> But $q + 1$ is greater than $1$, thus divisible by some prime
+      number not in the first $p$ numbers.\qedhere
     \end{enumerate}
   \end{proof}
