Sometimes, a chapter in a book, or an episode in a TV series, or a part in another type of work, shares its title with the work itself.
This often happens with the last chapter, episode or part. One of the reasons is that the title works as indication that the road is now complete, for example, if an essay's title refers to the main idea it's trying to prove, the last chapter would have the same title because all the arguments have been presented and now the conclusion represents the whole book, similarly to a fractal, where a part is identical to the whole.
Quite as often, as well, it's the first episode or part which bears the same title as the whole work. This is because the segment serves as introduction to the main character, setting, or idea of the work. In the case of TV shows, the reason may be that the first episode was originally made as the pilot for the whole series, so it's natural that it bears the same name.
Another reason to use this may be that the title of the work as a whole is part of a phrase, song lyric, poem, etc. that is divided among the chapter titles (i.e., a Compound Title). In this case, the partial titles are also Arc Words.
