In the case of Lydia's page, I do believe he locked it to keep from changing her character status because the page was free to edit before the argument. I don't feel that he should be the one to decide seeing as she is a main character whether he chooses to acknowledge it or not.

Now, as for the other pages you've mentioned, those pages are locked because people have been editing them with their own opinion as if they were facts.
