Why do we have the "Episode #" prefix in every episode's title? I looked through the wiki's logs and found that most of them were renamed to include this prefix by during July 2010, with the reason being "title needs to be more specific in case of conflict with other article titles." I can't see any conflicts arising from not using the prefix. In the past six years, have we avoided any naming conflicts as a result of using the prefix? If not, then is there another reason why we still use it?
