Including our Garbage... And corpses.
Hm, some IMDb Trolls really are downvoting all of the high-rated reviews. This is not Reddit, go there instead.
There were so many levels in this Glen Morgan written episode "Home Again", with the Humorous episode out of the way, we have as someone said "One Breath" but also elements of "Kaddish" and possibly "Arcadia". I don't see it as any kind of rehash or repeat of previous plot lines, because the mythology is remarkably different in each one.
We are responsible for what we create. Regardless of if it is a mound of trash, a child, a piece of art, a law, or a Homeless Shelter. Tim Armstrong from the bands "Rancid" and "Operation Ivy" is "The Trashman" - Hero of the Homeless, and creator of "Band-aid Nose Man" (John DeSantis) - An outward Expression of Trashman's beliefs, an expression which soon starts expressing a life of it's own, at the grisly expense of a few crooked politicians and "Art Stealers".
Meanwhile we have the return of Margaret Skully (Sheila Larkin)- And Dana dealing with that, the end result is that she starts thinking about William again. Was it the right thing to just give him away? At the time during Season 9, it was. But the Trashman's remarks stir up groaning too deep for words. At first he sounds like my neighbor when he gets drunk, until the "Profoundities" emerge, he's speaking directly to Skully.
The fact is, it is difficult to tell this story in 6 episodes. We've been through some of this in "William" and "The Truth" and there were some ironic parallels in Trashman's Lair, if we see what Skully sees there.
As a social statement, it's mostly about how the Homeless are fought over by two factions, lets call them the "red" and the "black" for now: It doesn't really matter if these people, played by Daryl Shuttleworth and Peggy Jo Jacobs are representing a political party or something else, Mulder basically identifies them right away as being motivated by the same thing: making money off of the needs of the Homeless, one wants to shunt them away to be forgotten and make money from them, the other wants to simply make money from them. And everyone involved eventually meets Mr. Band-aid Man.
It's also a little reminiscent of Season 6's "Arcadia" in which a man in charge of a homeowner's association is responsible for creating a huge Trash Monster. So in Kaddish, we had a bona-fide Golem, which was motivated by some kind of sense of loss and love and also empowered by Jewish Mysticism, Arcadia, in which the Garbagemonster was motivated by small infractions of someone's huge rule-book empowered by an eastern religion, eventually he is dealt with by the same unreasonable rules from his own book. Which usually happens when a religion keeps a "god-given" text that contains contradictory commands. This could be any religion.
But Skully's reflections at the denouement of this Episode pretty much say it outright, she is still responsible for William, and just as Margaret needed to talk to her youngest child, so too will Skully need to seek our her only remaining child. In all of this, have we forgotten Emily? But Emily's story is done, William's is at this point a big Question mark.
Musicwise, Glen Morgan once again shows his roots with Petulia Clark's "Downtown"
