Although there is only one accepted way of listing episode titles in articles, I keep seeing several forms of listing used:
The first is the correct way of listing episodes, as explained in the manual of style, but it seems that some people are either unaware of this, or occasionally forget. That's understandable (I do it too sometimes), but would everyone please try to keep the listing consistent? If you are creating an article, give the episodes the proper formatting, and if you come across an incorrectly listed episode, edit it or tell me and I'll edit it.
This doesn't apply to the episodes listed in the "Appearances" section of character articles, by the way.
