Was the Loner Leader in love with the Nearsighted Woman?

When David began his affair with the Nearsighted Woman, I was afraid they would be forced into the "Red Intercourse". Instead, the Leader just made her blind so the two of them would no longer share a trait and couldn't be together anymore. After that, she let the two of them do as they please, which seems like a pretty light punishment compared to what we saw others go through when they were caught having affairs.

Then I got to thinking. David and the Nearsighted Woman had a secret code they used to communicate with each other. In a similar manner, the Leader and the Woman spoke French to each other and seemed to be the only two who knew the language. In essence, both the Leader and David had their own ways to communicate with her. What are your thoughts?
