 \subsubsection{For $\p = \pr$:}
 By Desired Contents, above, $D \not\isin C$.
-So $C \nothaspatch \pr$.
+OK.
 
 \subsubsection{For $\p \neq \pr$:}
 By Desired Contents, $D \isin C \equiv D \isin L$
 (since $D \in \py$ so $D \not\in \pry$).
 
 If $L \nothaspatch \p$, $D \not\isin L$ so $D \not\isin C$.
-So $L \nothaspatch \p \implies C \nothaspatch \p$.
+OK.
 
 Whereas, if $L \haspatch \p$, $D \isin L \equiv D \le L$,
 so $C \zhaspatch \p$;
-and $\exists_{F \in \py} F \le L$ so this $F \le C$.
-Thus $\p \neq R \land L \haspatch \p \implies C \haspatch \p$.
+and $\exists_{F \in \py} F \le L$ and this $F \le C$.
+Thus $C \haspatch \p$.
+OK.
