The Steven Universe episode titles cannot possibly be real.

[snarp]

I mean, we already know they fiddle with the upcoming titles and descriptions to keep us confused. These are merely random evocative words and phrases slapped together to mess with us, none of them corresponding to any one real episode.

(Except for TBA and TBA, which will definitely be the actual titles of episodes 33 and 34. (Future Vision.))

If they are real, the ones with the most innocuous names are all about people being dismembered and screaming into the void, whereas "Monster Reunion" and "Gem Harvest" are just Steven playing Pokemon and Bejeweled, respectively.
