Because sometimes even the worst of days can be improved by the return of a loved one. Because sometimes that loved one is a cartoon horse for some reason. Because sometimes, just sometimes, people write standalone sequels to earlier stories but kinda want to kill themselves after actually reading the old stuff they wrote because seriously 1st person present tense what were they thinking I mean goddamn.

Because sometimes, people can't think of a half decent name so just make a poor euphemism out of an episode title, because that's totally original and everything.
